Chiller-based Dehumidifiers

Chillking®️ has been removing moisture from the air for twenty years. From paint spray booths to greenhouse gardens we have stabilized the relative humidity (RH) and controlled environment temperatures when needed. Chillking and our new division DehuKing understand the importance of space in the greenhouse. With the chiller located outside and using a small air handler or dehumidification air handlers we don’t waste your valuable space. Shadows are created when large objects are blocking the sun. Plus the space is better used growing crops. We developed an air handler that is small. A 25 ton air handler that has heat and cold, it is 24” x 30” x 30”L. We have smaller tonnage air handlers that are much smaller. The 25 ton will dehumidify producing up to 36 GPH to stabilize and control RH. It has two water lines that come from the chiller/pump station outside.

Any licensed technician can work on DehuKing chillers and Chillking chillers as they operate very similar to air conditioning such as package units. Our Chillking and DehuKing chillers have a Copeland® compressor or multiple Copeland® compressors, fan delay, hi-lo safeties, and numerous other features such as stainless steel fully insulated reservoir. Inside the greenhouse or building the air handler has a heat exchanger (HEX**) to remove humidity and drop air temperature for comfort. Be it for greenhouse, commercial or industrial applications we have the dehumidification method for you. If the air handler is designated as a dehumidifier it will have two HEX**, one heat exchanger is to chill the air and remove humidity while the other heat exchanger (HEX) is for hot water to re-warm the air and bring the air temperature back up. This is necessary because at times you need less humidity but no temperature change. Chillking and DehuKing are energy conscious, the hot water can be from heat recovery of discharged heat from the chiller. Boiler heat can also be used if already plumbed for heat. Adding heat to the air handler gives you a complete HVAC* system. Our dehumidifier air handlers are ETL listed and certified by Intertek®. No worries about the safety of the units and their operation. Chillking has been working with Intertek®️ since our founding. Quarterly visits to help us keep you safe and our standards at the highest levels.

Vertical Industrial dehumidification air handler. Intakes on one end and discharges out the other end.

We designed our dehumidification air handlers for all conditions. Everyone of our dehumidification air handlers are indoor or outdoor units that have the air intake on the lower cabinet side or end. The beauty of Chillking and DehuKing air handlers for dehumidification is that they can be set up how you prefer. Intake can be left side, right side, front or back. Discharge can be set up the same. For the larger units we offer a collar or extension that mounts to the intake register, then you can put the unit outside the greenhouse, push it up to a flat wall and the collar extension protrudes into the greenhouse. The top air discharge is set up the same. You choose the type air filters you want, they can be purchased at Walmart, Lowe’s or Home Depot. There are options for the type air discharge you want, adjustable louvres, duct collar, air deflector, or split deflector. Regular stainless steel legs that are adjustable for leveling or casters. If mounted to hang we can place hangers or mounting plates in numerous locations on the air handler. Greenhouse, industrial or commercial use air handlers and dehumidification air handlers can be purchased in galvanized, painted finish or stainless steel. DehuKing and Chillking has the products you need to control or produce a stable environment.

Mobile air handler, rear intake, top discharge. Or can be mobile dehumidification unit.

All air handlers and dehumidification air handlers must be fed by a glycol/water chiller system. DehuKing and Chillking chillers are energy efficient chillers. Matched to our air handlers we have seen EER*** numbers approaching 30. Twenty years ago home air conditioners were happy to reach a 10 EER. The better the rating the more money you save. Our chillers with the Chillking designed and built evaporator in tank (EIT) will exceed their tonnage rating by 10%. They must! Chillking and DehuKing guarantees the unit to produce 110% of its tonnage rating at 90F to 95F ambient conditions. You get additional tonnage for free. If a chiller can produce more than its tonnage rating you save energy. If it produces 10% more then it goes off 10% sooner. Our ten ton chillers is rated at 120,000 BTUs, it must produce a minimum of 132,000 BTUs. Our ten ton chillers normally test around 12 tons or 140,000 BTU. (One ton is 12,000 BTU)

In some cases with high volumes of air and a desperate need for at least a 30F drop in air stream temperature too much moisture may be removed from the air. When this happens moisture must be added to the air stream to bring humidity to the desired level. How does too much moisture get removed? In very large industrial commercial paint booths or paint rooms it is necessary to drop the temperate up to 30F on a single pass and sometimes even more. In Texas for example, we have had almost two full months over 100F, some days were 115F. With 115F ambient temperature and a desired 75F, a 40F temperature drop is required. Air in a paint room or booth cannot be recirculated because of paint particles in the air that would quickly coat the HEX and decrease the capacity to exchange heat. In such cases we often use double thick HEX slabs or double the square feet of surface contact area. One method slows down the air moving across the HEX thus allowing for a greater heat exchange. The other allows the air to move at the same speed but increases the surface contact area. Chillking and DehuKing have the expertise to size or design for your specific need, be it a greenhouse, commercial, industrial, medical, bakery, brewery, or distillery.

Small air handler, intake opposite end, front discharge.

All greenhouse, medical, and food processing require stainless steel surfaces that can easily be wiped down. DehuKing and Chillking has NSF certified products plus all air handlers are ETL listed for UL specifications. Our factories are inspected quarterly by Intertek®️ Corporation, an independent testing laboratory. Air handlers are available in 1 phase or 3 phase with 120v, 230v-240v, 208v-230v, and 460v-480v. Variable speed control available on some models. Flat fan assembly or squirrel cage blowers. Large industrial units have dual squirrel cages and belt driven motor. Casters in rubber, steel, or plastic are available, or pick from legs or skids. Ionizers, electrostatic filters, charcoal filters, and numerous fiber or pressed fiber filters can be chosen. We keep charcoal filters in stock for immediate replacement when needed.




*HVAC  = Heat plus Ventilation and Air Conditioning. Includes heat.

**HEX or HX = Air to water/glycol Heat Exchanger.

***EER = Energy Efficiency Rating. The higher the better.
