An updated portable heat pump that delivers 1.8 tons (21,240 Btuh) of heating capacity and 1.5 tons (17,700 Btuh) of cooling is available from Atlas Sales & Rentals, Inc. The SHAC Model 1811 portable unit provides supplemental heating in environments with ambient temperatures of 45°F and above -- unlike competitive units which need higher temperatures to operate. It also offers a small footprint, measuring just 20.25-in. wide x 42-in. deep x 42.5-in. high.

The Atlas portable unit runs on a 115-V/20-amp circuit and can switch over from heating to cooling at the touch of a button, for versatile "two-in-one" performance. It features an indoor/outdoor condenser which provides for maximum efficiency through a balanced condenser air pressure. Additional features include a high lift condensate pump, independent evaporator and condenser motors, and auto restart in the event of power failure. It provides an ideal way to deliver supplemental or "spot" heating to all types of buildings.
