DehuKing Greenhouse





Self-contained, free-standing dehumidification units

DehuKingTM came to be because of demand. Our founding company has been building dehumidification for twenty years but as a part of their chiller operations. In recent years there is demand for independent freestanding dehumidification machines. DehuKingTM is introducing a full line of dehumidifiers made of stainless steel and upgraded heat exchangers. Even the footprint is smaller than competing machines.

DehuKingTM coils are inside the cabinet, this protects the coils from damage. DehuKingTM coils are angled in order to get more coverage as the air is drawn across the coil. The cooled dry air is drawn across the condenser and discharged at close to the environment temperature. Condensed water is collected in a stainless steel pan and directed to remote tanks or plants.

CopelandTM compressors are used in DehuKingTM dehumidifiers, we use parts that are readily available locally. We use U.S. made parts when possible in our DehuKingTM dehumidifiers. GE motors, CopelandTM compressors, Emerson parts, A.O. Smith, Johnson controls, and many other fine American brands. DehuKingTM only buys an imported part when a U.S. built part is not available. Even then we make every effort to buy from an American company.

DehuKingTM builds dehumidifiers from 272 pints per day to 864 gallons per day. It is important to you that DehuKingTM does this as economically as possible. Power to condensation is listed on the spec’s page, watts used to a gallon condensed. You will find that we are very competitive in power used. Our parent company CHILLKING® has manufactured chillers that use less power for twenty years. DehuKingTM dehumidifiers are engineered to save energy, outperform the competition, and be superior in construction and quality.

In addition to these powerful dehumidifiers DehuKingTM manufactures chillers. When using a DehuKingTM Chiller an air handler that is set up for dehumidification is used. It has a chilled water coil and a hot water coil. These can have a very small footprint based on the type fan used. The DehuKingTM dehumidifying air handler is installed inside and the DehuKingTM Chiller is installed outside to make a very solid DehuKingTM dehumidifier. These perform at the same rate as our DehuKingTM package units.

DehuKingTM offers air cleansing, every DehuKingTM dehumidifier has UV. Every DehuKingTM has filtration. In addition DehuKingTM offers ionizers for the machines, ionized air increases plant growth and makes for stronger crops. In addition each machine can be ordered with charcoal filtration. It is important to us that your DehuKingTM machine does extras besides dehumidification. We at DehuKingTM want to increase air quality.

Some have used our machines to collect bathing water and even drinking water. TO BE USED AS DRINKING WATER REQUIRES NUTRIENTS ADDED. Disaster areas without power and working wells have ordered the DehuKingTM chiller dehumidifier combination and produced water. This is enough water for 86 people if they use 10 gallons per day each, very conservative use would allow for 160 people.

*Based on maximum relative humidity.

* Isolation panels increase efficiency by isolating evaporator environment from condenser environment.

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 DehuKingTM 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 DehuKingTM chillers and CHILLKING® chillers as they operate very similar to air conditioning such as package units. Our CHILLKING® and DehuKingTM 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 DehuKingTM 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.

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 DehuKingTM 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. If redundancy is a worry you can purchase all of our dehumidifier air handlers with UV light inside. Actually any of our air handlers can be purchased with UV on board. 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. DehuKingTM 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. UV optional.

All air handlers and dehumidification air handlers must be fed by a glycol/water chiller system. DehuKingTM 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 DehuKingTM 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 DehuKingTM have the expertise to size or design for your specific need, be it a greenhouse, commercial, industrial, medical, bakery, brewery, or distillery.

All greenhouse, medical, and food processing require stainless steel surfaces that can easily be wiped down. DehuKingTM 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. UV lights, 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.
