Description

Innovations in technology have resulted in much denser components packaging and smaller available panel sizes on which to mount air conditioners. The KOOLTRONIC TrimLine Series is the response to these new packaging demands with Narrow 10", 12", 15" and 17" width panel-mount air conditioners. In addition to being narrower than traditional air conditioner units, the TrimLine Series include the Condensate Evaporator and Low Temperature Control Thermostat as standard features and are available in all popular voltages and frequencies. The NP17, NP28, NP33 and Narrow-Mini models feature a Programmable Thermostat as a standard feature.

The TrimLine Series consists of two series of compact models, the NP Series and the NPT Series. The NP Series models offer capacities from 2,000 to 7,000 BTU/H and use CFC-Free R134a refrigerant. The NPT Series offers units with capacities from 4,000 to 16,000 BTU/H and use Zero Ozone Depleting R410a refrigerant. The TrimLine Series consists of models rated for NEMA 12 and NEMA 3R. Please check specifications for individual model approvals.

Outdoor or corrosive environments require weather protection and/or special internal and external protective features. Also see Guardian/GuardianX and Slimkool Series.

For extreme ambient temperatures and/or severely contaminated environments, the use of Water-Cooled Air Conditioners or Water-Cooled Heat Exchangers is recommended.

KOOLTRONIC also designs and manufactures a variety of air conditioners to meet unique specifications. We invite your inquiries about our modification and custom-design capabilities.

Many popular units are available as 3D solid models for customer system integration. Contact Kooltronic for details.

A non-drying adhesive coating traps a high percentage of particulate matter. These filters are reuseable, they may be washed and recoated with the appropriate filter recoating adhesive. Replacements are available for those which become damaged or otherwise non-serviceable.
