EnPlus offers a complete line of high efficiency horizontal and vertical units from 2.8 to 17.7 kW. Four cabinet sizes with a similar shape allow for easy layout and installation. Each unit is run-tested with water in the cooling and heating modes in the factory.

water-to-water units are designed to supply warm and/or cold water to auxiliary devices such as air handling units, fan coils, and radiant floor heating systems while maintaining the use of the water loop or geothermal type.

EnPlus produces water-to-water units in 11 sizes from 5 to 63 kW with three on figurations; heating only, cooling only or reverse cycle heating and cooling (heat pump). The unit is a single package with separate water connections for the boiler/tower (source) loop and the air handler(load) loop. Each unit is fully tested before delivery.

EnPlus offers a complete line of high efficiency units from 2.8 to 13.5 kW. Split type is specially design for the quiet application as the condensing unit with compressor can be separately installed away from the indoor unit . Each unit is run-tested with water in the cooling and heating modes in the factory.

Unique feature：

● Excellent heat transfer, the key to rely on the convoluted multi-head inner tube manufactured in a patented process. China Patent No. ZL03229545.6
● The resulting convoluted tube has increased heat transfer surface area as per unit length yet still permits full around flow of both water and refrigerant along helix inner tube for improve performance.

● Turbulence imparted by the convolutions to both the water and refrigerant flows for control fouling to be sink in surface.The net result is a highly effective,compact heat exchanger with superior anti-fouling characteristics.
● The water and refrigerant are converse flow to makes excellent heat transfer effective of heat exchanger when condensing.
● Standard sizes is conducive to saving space for nominal 6000BTU through 84000BTU.
● The inner tube can be made of copper or B10 cupronickel, shell tube in steel.Copper inner tube is available in fresh water and cooling tower application while cupronickel is available for ground and sea water application.
● Extek coaxial coils are approved by Underwriters Laboratories,Inc.(U.L.)for use with refrigerants R12,R22,R407c R410a and other new refrigerants.
