INQUIRE ABOUT PRODUCT

HOW IT WORKS

This product is developed as a sustainable solution for the animal husbandry industry. By integrating the function of air intake and air exhaust, it is particularly suitable for environments which need a large amount of fresh air from outside. Meanwhile, it greatly improves the breeding environment and effectively solves the contradiction between ventilation and heat loss.

There are two fans inside of the heat recovery ventilator, one discharges the humid air in the room while another intakes fresh cold air from outside. When hot air and cold air passes through the heat exchange core, the fresh air is preheated, which can reduce the cost of heating and minimize cold stress.

 

  • Air flow: 2×2,500m3/hr
  • The box material is Zinc Aluminum Steel;
  • Both air inlet and outlet are filtered by primary filter (easy disassembling and cleaning) to prevent blockage of the heat exchange core and guarantee the quality of fresh air from outside;
  • Aluminum alloy spherical air outlet is adopted for the fresh air inlet, with the long distance of airblowing, omnidirectional wind can be adjusted with 180-degree angle, ensuring no dead point of air supply;
  • Excellent heat transfer performance and high heat transfer efficiency, special anti-corrosion treatment, durable, easy to disassemble and clean;
  • The exhaust fan and inlet fan can tolerate multiple environments, like high-humidity and corrosion breeding houses;
  • Automatic defrost prevents the heat exchange module from being blocked, and the defrost time can be set automatically according to the actual temperature conditions;
  • Fitted with an environment controller which can be automatically turned on and turn off;
  • Solid and reliable structure, easy to disassemble and repair.

Select the number of heat exchangers at the maximum load to meet the minimum ventilation for Stage 1 and/or Stage 2. For all-in, all-out livestock houses, this varies as the animals grow. Determine the number of heat exchangers (maximum airflow) by adult animals and run the appropriate number of heat exchangers (reduced airflow) for young animals.

The biggest challenge facing heat exchanger application in a poultry house is the amount of dust
encountered in the air. Dust in the exhaust airstream, if not handled properly, will degrade the
performance of any heat recovery system. Proper handling of dust is critical to the success of a heat
recovery system application. Traditional flat­plate heat exchangers require upstream filtration systems
on the warm exhaust air side to intercept the dust (from indoor air) before it enters the heat exchangers.
After a grow­out, exchanger cores need be cleaned using compressed air or water, depending on the
equipment designs. Regular cleaning effectively removes dust and rejuvenates the cores.

  • Heating power of poultry house(kW)=volume(m³)*0.07kW/m³
  • The temperature in a house with a well-designed forced-air space heating system is relatively uniform from floor to ceiling and around the house. Poultry houses and pig houses commonly are rated 30kW to 70kW. The industry standard is to provide around six to eight heaters in a 120 long broiler house, rather than four large heaters. This improves heat distribution in the house.
  • Large heaters are only marginally more expensive than units with half the kW capacity, so it is common to over-design for houses that will contain brooding chicks. 
  • Space heaters operate at low gas supply pressures. Heated air is distributed with the heater fan and through mixing with the incoming ventilation air jet. Maintaining warm temperatures near the floor during early brooding is a common problem with space heaters.
  • Broiler management guidelines recommend starting air temperatures of 32–35°C at day 1. Every day thereafter, the guidelines recommend decreasing air temperature incrementally until a final temperature of 19–21°C is reached at around day 27 and maintained for the remainder of the growout.
  • Most space heaters use interior air and are unvented, which means they exhaust carbon dioxide, moisture, and incomplete combustion products directly into the building. Approximately 1.7 kg of water vapor is produced per kg of propane gas combusted. Thus, to prevent moisture accumulation caused by unvented heaters, it is recommended that minimum ventilation rate be increased by 14.5m³/h per kW heater capacity.
  • Stir fans are commonly installed near the ceiling to circulate this hot air back to the litter where it is useful to chicks. In some instances where adequate temperatures cannot be maintained, both space and radiant heat systems are used.
  • Thermostat location is important to maintain uniform temperature and energy savings.

INQUIRE ABOUT PRODUCT

HOW IT WORKS

This kind of gas room heater is a stand-alone appliance serving to heat an individual small space and capable of operating on propane or natural gas.

The equipment usually includes a heat exchanger, through which a fan blows air from the room to be heated. 

Combustion air comes from outside is preheated when the flue is forced to be discharged outdoors, so there is no worries of hypoxia and CO poisoning.

  • Natural gas or LPG.
  • Rates 5/7/12kW
  • Wall mounted or free-standing installation
  • Combustion air comes from outside is preheated when the flue is forced to be discharged outdoors
  • Room air is heated quickly with high efficiency by forced circulation
  • 12VAC/24VAC low voltage control system
  • Easy operation control panel on heater with separate remote-control device and timer
  • Overheating protection, flame monitor, exhaust pipe clog protection
  • Heating area: 20-70m2

Heating Area Volume & Climate Zone

The required kW output required is primarily dependent upon the area to be heater and the climate zone in which you live.  

The following rough guide assumes your ceilings are no higher than 2.4M:

Very Cold Zone: 1kW output required for each 8.5m²

Cold Zone: 1 kW output required for each 10m²

Cool Zone: 1kW output required for each 13 m²

Mild Zone: 1kW output required for each 16m²

Adjustment Factors

The indicated gas heating areas would be adjusted down by 5% for each of the following conditions: house built on pillars (non-slab), no carpets on floors, no drapes on windows or a ceiling height exceeding 2.4m. Deduct an additional 10% if the area does not have ceiling insulation. Please note that this is only a guide and individual home designs and situations may vary.

Gas Heater Sizing Example #1: 

You live in the Cold Zone and you want to heat an area 5m X 10m, which equals 50m².

Because 1kW will heat 10m², you should need a heater with a 5kW output.

Gas Heater Sizing Example #2: 

Same as the previous example but in this case your ceilings are over 2.4m and you have wood flooring instead of carpeting.                            You would need to deduct 5% for each of these two items. So, instead of 1 kW heating 10m², it would heat 9m² (10% total reduction). This means you would need a heater with 5.6 kW of output (50 ÷ 9).

  • The minimum clearance between the room heater and the combustibles must meet the manufacturer’s requirements
  • Reserve enough space for maintenance
  • The exhaust pipe is inclined downward by minimum 3°
  • The outdoor part of the exhaust pipe is kept away from combustibles and cannot be covered or shaded by snow
  • When installing on the wall, the bottom of the heater is 200-500mm away from the ground
  • Gas leaking alarm and emergency gas shut-off valve are highly recommended.

INQUIRE ABOUT PRODUCT

HOW IT WORKS

A unit heater is a stand-alone appliance serving to heat a given space and capable of operating on propane or natural gas.

The equipment usually includes a heat exchanger, through which a fan blows air from the room to be heated. There are two types of indirect-fired heaters, indirect-fired axial heaters (WAB) and indirect-fired centrifugal heaters (WCB). The temperature rise is about 28°C and 36°C, respectively. The air flows and the blowing distances are much greater with a centrifugal fan, and sometimes designed with a duct to distribute the warm air.

 

  • Natural gas or LPG.
  • Rates 50/80/150/200/300/400 x1,000 Btu/hr or 15/23/44/58/88/117kW
  • Inshot burner makes the combustion more complete with lower CO and NOx.
  • Heat exchanger made by aluminized steel or stainless steel pipes.
  • Reliable Direct Spark Ignition.
  • The 12VAC low-voltage ignition controller, specially developed for HVAC industry, all troubleshoots can be easily identified by the indicator lights
  • Safer and reliable low-voltage 24 VAC combination gas valve with 100% shut off.
  • Flameout protection, fan malfunction protection, and overheating protection.
  • Special baffles in the heat exchanger can enhance the heat exchange efficiency.

Heating Power: 

Warehouse: 25-35 Btu/hr per ft2 or 80-110 W/sqm

Mechanical workshop: 40-60 Btu/h per ft2 or 120-180 W/sqm

Here are the criteria to consider in selecting the units:

  • Installation height;
  • Positioning;
  • Axial fan or centrifugal blower
  • Heating power;
  • Combustion: sealed or unsealed combustion;
  • Venting: combustion products are usually vented outdoors.

It is always best to start with a pre-installation checklist; a list of things to check before an installation takes place. The following is a basic checklist and is meant to serve as an example:

  • Pick a location that is suitable for the unit that is being installed.
  • Make sure that venting requirements can be met.
  • Check for structural issues that may affect the installation of piping or duct work.
  • Plan a gas piping route, including pipe sizing, that will properly supply the system.

INQUIRE ABOUT PRODUCT

HOW IT WORKS

A high intensity infrared unit heats by radiant heat. The energy is spread by radiation: its effect on the human body is rather like being exposed to the sun. Like the light from a lamp, infrared radiant heat is directional and warms every object in its path, depending on the nature of its surface. The infrared radiant heat traverses the ambient air without losing its energy until the moment it meets an object.

Air and gas mix into the venture chamber to create a flameless combustion on the ceramic tile surface. The radiant surface temperature can reach 900°C and convert up to 60% of the gas input into radiant heat.

  • Natural gas or LPG.
  • Rates 9.5/18/28.5/36/46.5kW.
  • Unique pattern high output ceramics.
  • Reliable Direct Spark Ignition with 100% gas valve shut off.
  • Entire construction is non-corrosive aluminized steel.
  • High-polished aluminum reflector maximizing radiant efficiency.
  • Modular burner head construction.
  • Stainless steel venture and aluminized steel burner.
  • Performance enhancing screens on all models.
  • 15°-35° tile mounting.

Heating Power: 

Warehouse: 80-110 W/sqm

Factory: 120-180 W/sqm

Combustion: Non-sealed combustion (the combustion air is taken directly from the space to be heated and the combustion products are released into that same space).

Venting: The combustion products are vented indoors.

  • Minimum clearance to combustibles must be complied with, according to Keywarm HVAC.
  • Minimum height to be respected, according to Keywarm HVAC.
  • Installation is not recommended in places where there are chlorine products, solvents or explosives, but certain models are suitable for that type of environment.
  • The combustion products are vented indoors with additional ventilation. Usually, this calls for an interlock between the appliance and a mechanical extractor fan.   A fresh air supply unit needs to be installed in order to maintain an acceptable level of CO2 (5,000 ppm). For more details, consult the manufacturer’s Installation Guide.
  • The ventilation rate stipulated in Code B 149.2 is 300 ft3 of air per minute per 100,000 Btu/hr or each kW per 22m³/h fresh air of high intensity infrared installed.

INQUIRE ABOUT PRODUCT

HOW IT WORKS

The water gun(s) start first, when high pressure water passes through equipment’s heat exchanger, the thermostat calls for ignition. Then the combustion fan starts to pre-purge. The ignition control system starts to ignite and burn after the safety inspection. The high-temperature flue gas heats the heat exchanger, and the heat exchanger absorbs heat and transfers it to high-pressure water to produce high-temperature, high-pressure hot water. The combustion will stop when water temperature reaches the thermostat set-point during washing or when the water gun(s) stop.

 

  • Heat exchange system: High efficiency heat exchanger with double-layer coils. Galvanized or stainless steel pipes are available.
  • Combustion system: Downward flame, two-loop heating, high efficiency and energy saving.
  • , extremely low content of CO and other harmful oxides in the flue gas, and backfire avoided.
  • All-round water protection: water pressure protection (over/low pressure), water flow protection (over/low flow), water temperature and high temperature protection, dry heating protection, etc.
  • Combustion safety: Pre-purge and post-purge cycles. Ignition failure safety protection, accidental flameout protection, fan failure protection.
  • Control system: 12VAC low-voltage ignition and 24VAC gas valve are safe and reliable, and is convenient for daily maintenance.
  • Anti-rust treatment heat exchanger coil (stainless steel optional)                                                               
  • Rear-mounted boiler, cold water flows through the pump then heated by the boiler, which avoids accelerated aging and damage the sealing of the pump.
  • Easy maintenance and quick replacement of parts.

Heating Power, Water Flow Rate are two major factors of a boiler: 

  • 88kW, 15L/min.
  • 105kW, 21L/min.
  • 130kW, 30L/min.

Once your proper PSI value is established, based on the type of job you are completing, you can increase your boiler’s  to cut down on cleaning time. Below are a few common PSIs used with various surface cleaning duties:

  • Concrete cleaning: 3,000 to 3,500 PSI
  • Car cleaning: 1,200 to 1,900 PSI
  • Wood cleaning: 2,000 to 3,000 PSI depending on hard wood or soft
  • Trucks and tractors: PSI of at least 1,800
  • Livestock shelters: PSI of at least 3,000
  • Decks, fences, and siding: PSI of at least 2,000
  • Paint stripping, construction-site maintenance, graffiti removal: 3,200 to 4,200 PSI

Each boiler comes with following safe functions:

  • Excess pressure is released by a safety valve.
  • An exhaust gas temperature limiter turns off the system if the temperature istoo high.
  • The flow switch starts the boiler if the quantity of water is sufficient and stops it if the quantity of water is insufficient.
  • The pressure switch starts the boiler by reaching the minimum pressure.
  • All safety devices mentioned before are connected in series. That means if one of the elements has a malfunction the boiler does not start. This guarantees the highest level of safety.
