## Equipment

- [Dry Coolers](https://kuhlwerx.com/products/dry-coolers/): Reject process heat to the air. No tower, no makeup water, no basin. Best for: Closed-loop process cooling, data center free cooling, engine and generator jacket water, and any site where cooling tower water use or water treatment is a problem.
- [Condensers](https://kuhlwerx.com/products/condensers/): Condense refrigerant outdoors on a V-bank that keeps the footprint down. Best for: Remote air-cooled condensing on HFC and ammonia refrigeration plant, cold storage and process refrigeration.
- [Air-Cooled Heat Exchangers](https://kuhlwerx.com/products/air-cooled-heat-exchangers/): CO2 gas coolers and oil coolers, on the same coil and fan platforms. Best for: Transcritical CO2 refrigeration and hydraulic, lubricating and turbine oil systems that need fluid held to a setpoint without water.
- [Industrial Unit Coolers](https://kuhlwerx.com/products/unit-coolers/): Hold air temperature in a room that has to stay at a number. Best for: Cold storage warehouses, freezers, process rooms and food plants on HFC, CO2, ammonia or glycol.
- [Dual Discharge Unit Coolers](https://kuhlwerx.com/products/dual-discharge-unit-coolers/): Throw air two ways from one low unit, where a single throw leaves a warm end. Best for: Packing rooms, processing halls and cold work areas where people need even, low-velocity air under a low ceiling.
- [Blast Freezers](https://kuhlwerx.com/products/blast-freezers/): Pull product down to frozen fast, in a spiral, a tunnel or a freezing room. Best for: Spiral freezers, freezing tunnels and blast rooms in food processing.
- [Ripening and Pre-Cooling Coolers](https://kuhlwerx.com/products/ripening-precooling-coolers/): Push air through the stacked load, not around it, so the whole pallet moves together. Best for: Banana and avocado ripening rooms and forced-air pre-cooling of packed produce.
- [Customized Heat Exchangers](https://kuhlwerx.com/products/custom-heat-exchangers/): When nothing standard fits the duty, the fluid or the space. Best for: OEMs and plants that need a coil built to a drawing, in materials or sizes a catalog unit does not cover.

## Guides

- [Dry cooler or cooling tower](https://kuhlwerx.com/guides/dry-cooler-vs-cooling-tower/): Choose a dry cooler when water use, water treatment or freeze risk matters more than the lowest possible fluid temperature. Choose a cooling tower when the process needs fluid colder than the outdoor dry-bulb on the design day. Adiabatic dry coolers sit between the two.
- [How unit cooler capacity is rated](https://kuhlwerx.com/guides/unit-cooler-ratings/): US unit cooler capacity is rated in Btu/h or MBH at 10°F TD, where TD is the entering air temperature minus the saturated suction temperature. Capacity scales with TD, so the rating converts to other conditions with simple proportion.
- [How to size a dry cooler](https://kuhlwerx.com/guides/how-to-size-a-dry-cooler/): To size a dry cooler, fix the heat load, the fluid flow and temperatures, and the site design ambient. The leaving fluid temperature minus the ambient gives the approach, and the approach sets the coil size.

## Questions and answers

- Q: What does KUHLWERX sell?
  A: KUHLWERX supplies and supports UL approved industrial cooling equipment in North America: dry coolers, condensers, CO2 gas coolers, oil coolers, industrial and dual discharge unit coolers, blast freezers, ripening coolers and heat exchangers built to print, rated at 60 Hz and sized to each project.
- Q: Are KUHLWERX units UL approved?
  A: Yes. KUHLWERX equipment is UL approved. The range also carries ISO 9001, CE and RoHS.
- Q: Do the units run on US 60 Hz power?
  A: Yes. Ratings are at 60 Hz. Units use EC fans on 208-230 V or 460 V supply, and fans of 49 in and larger run on a VFD, so rated airflow and capacity hold on US power.
- Q: Where is KUHLWERX located?
  A: 27530 US-31, Flomaton, AL 36441. KUHLWERX supplies and supports equipment across North America.
- Q: Do you publish prices?
  A: No. Every unit is sized to the heat load, fluid and site conditions, so the price depends on the selection. Send the numbers and a sized quote comes back.
- Q: What do you need to quote?
  A: The heat load in Btu/h or MBH, the fluid or refrigerant, flow and temperatures, the design ambient, the electrical supply and any sound or footprint limit. Rough numbers are fine.
- Q: What is the capacity range?
  A: From a 7 MBH unit cooler to dry coolers over 14,500 MBH per unit.
- Q: What is the difference between a dry cooler and a cooling tower?
  A: A dry cooler is closed loop and uses no water, but cannot cool the fluid below the outdoor dry-bulb temperature. A cooling tower evaporates water and can approach the wet-bulb temperature, at the cost of makeup water, blowdown and water treatment.
- Q: What does 10°F TD mean on a unit cooler rating?
  A: TD is the entering air temperature minus the saturated suction temperature. US unit coolers are rated at 10°F TD. Capacity scales with TD, so a unit at 15°F TD delivers about one and a half times its 10°F TD rating.
- Q: Which refrigerants are supported?
  A: HFC and HFO blends, CO2 and ammonia, plus water and glycol. Published HFC ratings are on R404A and R507A; lower-GWP refrigerants are selected per project.
- Q: How does the AIM Act affect refrigeration equipment?
  A: Under the AIM Act, the EPA is phasing down HFC production and limiting high-GWP refrigerants in new systems, sector by sector. Tell us the refrigerant the system is designed for and the selection is run on it.
- Q: How do I read a KUHLWERX model code?
  A: Left to right: family, medium or arrangement, size, then build. KUC-H017-116-F6R4 is an industrial unit cooler, HFC, 17 MBH at 10°F TD, one 16 in fan, 6 fins per inch, 4 rows.
- Q: Can you build a coil to my drawing?
  A: Yes. Coils and heat exchangers are built to print in copper, stainless, cupronickel or titanium tube, up to 39 ft of finned length.
