Commercial refrigeration Air Cooled Screw Chiller Refrigeration For
Air Conditioner
1. Description:
Air cooled chillers are the workhorse for supplying chilled water
to air handling units in schools, offices,
government facilities and many more. Desired for their simple
design, easy serviceability and relatively
low cost/ton, these systems reside outside on a roof or the ground
near other buildings or residential areas.
Asa result, quiet operation is typically critical to meet code
requirements and avoid neighborhood complaint.
We go the extra mile to provide air cooled chiller solutions that
address more than acoustic performance
at your property line.
1. Capacities from 20 to 400+ tons.
2. When configuring a unit for a small footprint or to retrofit an
existing air cooled chiller application,
3. we can configure the cabinet size, chiller, piping, and pumps
for easy connection
4. Reliable scroll and screw compressor selections help you match
the right technology to the right
application for optimum energy efficiency and reliability
5. R-407C and R-410A options help you optimize energy efficiency
and environmental requirements
Aluminum, copper, and coated fins to meet all requirements
including corrosive environments
6. Shell-and-tube and brazed-aluminum heat exchangers afford
flexibility in size, cleanability and location
7. Factory-mounted DDC controls with standard building automation
protocol interfaces
8. Cabinet and frame construction to meet your needs: steel,
aluminum, and stainless-steel options
