What we need to size your unit
You'll talk to the people who design and build the equipment — no dealer layers. The more of this you can tell us up front, the faster we can spec it.
- What you're cooling — a space, a process, or people.
- Approximate airflow or square footage of the area.
- Your location and climate — it drives how big a temperature drop to expect.
- Available power — single or three phase.
- Move or stay put — whether the unit needs to roll, hang, or mount through the wall.
Don't have all of it? Call anyway. Square footage and your city are usually enough for us to point you at the right model and a ballpark.
Not sure a portable is the right form factor at all? Stationary systems cover permanent installations, and specialty coolers exist for applications nothing off the shelf fits.
Not what you're looking for?
Stationary Systems
RTA series coolers from 9,000 CFM, retro-fit wet sections, and packaged units built to spec.
Condenser Pre-Coolers
Drop condenser intake air temperature, lower head pressure, and let your compressors work less for the same tonnage.
Replacement Media
Munters CELdek® rigid media in standard and cut-to-order sizes for the units you already run.
Which model fits your space?
Tell us the square footage, the heat load, and the power you have available. We'll size it and quote it straight from the factory.
