The Extraordinary Premium EW Hydronic Heat-Pump System
Hydronic heating and cooling systems have long set the industry standard for comfort and flexibility. Whether the application includes radiant heating, forced-air fan-coil units, domestic hot-water heating or process heating/cooling loads, the Premium EW can fit every application, from simple to complex. Sophisticated microprocessor controls and state-of-the-art components ensure many years of virtually maintenance-free operation. The Premium EW also can supply hot water for pools, spas and ice-melt under sidewalks.

Because it doesn't burn fossil fuels, the Premium EW emits no harmful greenhouse gases, which are associated with global warming. No flames. No fumes. No odors. No danger from carbon monoxide. The GeoSmart Energy EW is the best in the business.

>DESIGN FEATURES/BENEFITS

Operating Efficiencies

• The Premium EW uses environmentally responsible R-410A refrigerant.
• An optional desuperheater generates hot water at considerable savings while improving overall system efficiency.
• A high-stability, bi-directional expansion valve provides superior performance.
• Efficient scroll compressors operate quietly.
• An oversized coaxial-tube water-to-refrigerant heat exchanger increases efficiency.

Flexibility

• The Premium EW is designed to operate with load temperatures of 30° F to 130° F (30 –100 EST, 50 – 130 ELT).
• Source side-flow rates are as low as 1.5 GPM/ton for well water (50° F min. EWT).
• Dedicated-heating, dedicated-cooling and heat-pump models are available.
• Modularized unit design and master/slave controls allow optimum capacity-matching and staging.
• Premium EW units are stackable for space conservation.
• Their compact size allows installation in confined spaces.
• Front or rear plumbing connections are provided.
• The Control Panel location is reversible.

Factory Quality

• Heavy-gauge steel cabinets are finished with durable poly paint for long lasting beauty and service.
• All refrigerant brazing is performed in a nitrogen atmosphere.
• All units are deep-evacuated to less than 150 microns prior to refrigerant charging.
• All joints are helium leak-tested to ensure an annual leak rate of less than 1/4 ounce.
• The evaporator heat exchanger, refrigerant suction lines, desuperheater coil and all water pipes are fully insulated to reduce condensation problems in low-temperature operation.
• Sound attenuation features include an isolation-mounted compressor and a high-density, weighted sound blanket.
• Safety features include high- and low-pressure refrigerant controls to protect the compressor ... and hot-water, high-limit, desuperheater pump shutdown.

Options & Accessories

• A desuperheater with an externally mounted pump and water heater plumbing connector.
• A closed-loop, source-side, circulating-pump kit.
• A closed-loop, load-side, circulating-pump kit.
