50YEW Water-To-Water Design Features
The 50YEW series is unlike any other water-to-water heat pump on the market today. The large operating map of the scroll compressor allows high temperature operation, up to 145°F [63°C] leaving load water temperature even at 32°F [0°C] entering source water temperature. The combination of a coaxial (tube-in-tube) heat exchanger for the source (ground loop) side and a brazed plate heat exchanger for the load (heating/hot water) side provides very high efficiencies. Integral controls for hydronic heating and domestic water heating avoid the need for external microprocessor-based controls for outdoor temperature reset, warm weather shutdown, staging and other controls.
The 50YEW has an extended range refrigeration circuit, capable of ground loop (geothermal) applications as well as open loop (well water) applications. Standard features and factory-installed options are many. Unique application-specific controls make the 50YEW series ideal for hydronic heating and domestic hot water generation. The heating-only refrigeration circuit is optimized for high water temperatures, heating efficiencies, and capacities.
The dual level compressor isolation mounting system, insulated compressor enclosure, and compressor discharge muffler make the 50YEW series one of the quietest water-to-water heat pumps
available. The attractive “Euro-style” cabinet allows the unit to fit into any decor.
Application Flexibility
•Capacities 10kW [32,600 Btuh].
•High temperature scroll compressor, up to 145°F [63°C] leaving water temperature.
•Ultra high efficiencies (4.2 COP at ground loop conditions; up to 5.5 COP at ground water conditions).
•Built-in programmable controller with OutdoorTemperature Reset and Warm Weather Shutdown.
•Large, back-lit digital user interface.
•Rugged coaxial (tube-in-tube) “Source” heat exchanger (copper or cupro-nickel).
•Close approach temperature brazed plate stainless steel “Load” heat exchanger.
•Dual level compressor isolation, compressor enclosure, and discharge muffler for Ultra quiet operation.
•“Euro-style” cabinet for attractive look.
•Insulated cabinet with foil backed insulation for ease of cleaning.
•Flush-mount FPT fittings, secured to the cabinet (no backup wrench required).
•TXV metering device.
•12-point low voltage terminal strip for ease of installation.
•ETL safety listing.
•Wide variety of options including internally factory installed Domestic Hot Water Mode, Load and Source side pumps with expansion tanks,VSFP (variable speed floor pump connection) Controls and Cupro-Nickel Source Heat Exchanger.
Service & Installation Advantages
•Hinged front access door and 3 removable panels for ease of installation and service.
•Galvanized steel construction with protective powder coat paint and hinged front access door.
•Bi-directional thermal expansion valve.
•Puron® HFC-410A zero ozone depletion refrigerant.
•Circuit breaker protected 75VA control transformer.
•High and low pressure service ports on refrigerant circuit.
•Accurate refrigerant sensing freeze protection.
Factory Quality & Certifications
•All units are built on our Integrated Process Control Assembly System (IPCS).The IPCS is a unique state of the art manufacturing system that is designed to assure quality of the highest standards of any manufacturer in the water-source industry. Our IPCS system:
a.Verifies that the correct components are being assembled.
b.Automatically performs special leak tests on all joints.
c.Conducts pressure tests.
d.Performs highly detailed run test unparalleled in the HVAC industry.
e.Automatically disables packaging for a “failed” unit.
f.Creates computer database for future service analysis and diagnostics from run test results.
•All units are water run-tested in all modes to insure efficiency and reliability.
•Heavy gauge galvanized steel cabinets are epoxy powder coated for durable and long-lasting finish.
•All refrigerant brazing is done in a nitrogen atmosphere.
•All units are deep evacuated to less than 100 microns prior to refrigerant charging.
•All joints are both helium and halogen leak tested to insure annual leak rate of less than 1/4 ounce.
•Coaxial heat exchanger, refrigerant suction lines and all water lines are fully insulated to eliminate condensation problems in low temperature applications.
•Noise Reduction features include: dual level compressor isolation, insulated compressor compartment, interior cabinet insulation using 1/2” coated glass fiber, and variable speed fan.
•Safety features include: high pressure and loss of charge to protect the compressor, condensate overflow protection, freeze protection sensors to safeguard the coaxial heat exchanger and air coil, hot water high-limit and low compressor discharge temperature switch provided to shut down the hot water generator when conditions dictate. Fault lockout enables emergency heat and prevents compressor operation until thermostat or circuit breaker has been reset.
•10-year limited warranty on major refrigerant circuit components, Optional extended warranties available.
•AHRI/ASHRAE/ANSI/ISO 13256-2 certified.
•NRTL & CSA listed.
•US EPA “Energy Star” compliant.
•ISO 9001:2000 Certified.
Options & Accessories
•Full Condensing Hot Water Generation With Internal Secondary Heat Exchanger and Potable Water Circulating Pump.
•Factory Installed “Load” and “Source” Pumps.
•Factory Installed ExpansionTanks.
•Cupro-Nickel Source Water Coil.
•Extended Labor Allowance and Service Warranty.

50YEW operating parameters are as follows: Min Source EWT = 20°F; Max Load LWT = 145°F (see application section for design guidelines). Interpolation is permissible; extrapolation is not.
Operation below 40°F EWT (source) is based upon 15% methanol antifreeze solution. All performance data is based upon the lower voltage of dual voltage units.
Antifreeze for source water is required for operation in the shaded area and all source EWTs below 40°F.
