Our Heat Pump Boilers, using our patent pending Cold Climate Heat Pump™ system, can extract heat from nearly any source such as a waste stream or even outside air at 20°F below zero (-29°C).  Then they can deliver the heat at temperatures ranging from 75°F to 220°F (25° to 105°C) and do it efficiently.  We offer standard sized systems for heating domestic hot water for homes, hotels, apartment houses, hospitals, restaurants, industry, jails, dorms, nursing homes or any application needing a good and reliable supply of low cost hot water. 

In addition, we can custom build an industrial or commercial system that can be tailored to the exact job requirements. Operating at special high and/or low temperatures or needing unique control sequences. Whatever the job, we can design a system to meet your needs.

Pasteurization of bottled drinks using the common “hot fill” process  can be easily done with a NRT specialized heat pump.  Heat is extracted from the water cooling the bottles after filling and that heat is used to heat the product to 215°F (102°C) drastically reducing the energy consumption and carbon footprint.

Specialized Liquid and Water Chillers
Our chillers are custom built to meet the needs of those with special requirements such as corrosion resistance in heat exchangers, special control requirements, unusual temperature operation. We have built chillers using titanium, stainless steel, cupronickel as well as common copper and steel heat exchangers. If easy cleaning of the heat exchangers is required, we can do that. Whatever the need, we can provide a specially built chiller at a surprisingly low cost.
