^{Energy Efficient}

FHP Commercial
EP Model

Plenty of options are available for the highly customized EP Series allowing you to get the heat pump that best fits your needs at a cost effective price.

Overview
Design Features

Features Designed for any Application

Industry-leading single-stage efficiencies, standard features, and a variety of options - providing energy efficient solutions to accommodate your building requirements. The EP Model, water-to-air heat pump offers high efficiency, value added features and a single stage compressor (scroll type 1 1/2 - 6 ton size). An optional ECM constant airflow fan motor can give you the flexibility, performance and quiet operation needed to meet the expectations of your clients.

ECM Constant Airflow Fan Motor

The high efficiency Electrically Commutated Motor (ECM), available in 1/3hp to 1hp, provides constant airflow in a wide static pressure range up to 1 in.w.g. Optional in all unit sizes except 1/2 through 1 ton, this motor is a great choice in high filtration applications. The motor has a soft start/stop feature, keeping noise to a minimum. Passive dehumidification can be achieved with the constant airflow ECM by reducing nominal airflow by 15%. This control feature lowers air coil temperature and prevents over-cooling of the space when in dehumidification mode. The constant airflow ECM requires a neutral wire in a 460V application.

Blower and Motor

PSC blower motors are standard on unit sizes 1/2 through 1 ton. Multiple speed constant torque ECM motors are standard on units sizes 1 1/2 through 6 tons, allowing the user to select the correct speed to deliver the specified airflow and the design system static pressure.

MERV-8 and MERV-13 Filters

The optional 2" MERV-8 or -13 filter is most advantageous for premium air filtration on commercial HVAC projects. High efficiency filtration is a cost-effective way of upgrading air quality while maintaining low pressure drop and sustaining long service life. These filters effectively remove up to 98% of airborne matter, such as fine particulates, bacteria, smoke, gases and allergens including dust mites, pollen, mold spores, dust and smog. MERV-8 and MERV-13 rated filters are a minimum requirement for EQ credits 3.1 and 5 on LEED® projects.

DDC Controls

The optional factory mounted DDC Controller is preprogrammed and installed on the unit with the Unit Protection Module (UPM) to be job site ready. With a factory-supplied DDC wall sensor, the unit will operate in a 100% stand-alone control mode or connect to a Building Automation System (BAS) using open protocols BACnet™, Modbus, N2 or LonWorks® (with an optional Lon card).

DDC Room and Zone Sensors (optional)

To complement the controller, Bosch Thermotechnology Corp. offers a line of intelligent FHP space sensors, which provide precision measurement and communication capabilities in an attractive low profile enclosure.

Quiet Comfort

Floating Compressor Base - Reduces vibration and noise transmission from the compressor to the structure
Closed-cell Foam Insulation (option) - Helps to provide cleaner, fiber-free air and reduces sound transmission
Compressor Blanket (option) - Offers optimum low sound levels (not available on smaller units with rotary compressor)

Service Friendly

Blower Inlet Ring - (available in 015-070 only) Allows quick servicing of blower fan motor without disassembly of blower housing
Insulated Divider - Separates the compressor and blower sections, allowing the unit to be serviced easily during operation
Schrader Charging Valves - Facilitates service diagnosis by allowing the connection of refrigerant hoses quickly and securely

Robust and Durable Construction

Galvanized Steel Cabinet - Provides strength and corrosion protection
Evaporator Coil Protection with DuoGuard™ (option) - Tin electro-plated copper tubing with high-tech polymer coated aluminum fins that aid in protecting the evaporator coil from most forms of corrosive elements in the air stream
Stainless Steel Drain Pan - Resists cracking and corrosion which provides long-lasting reliability for condensate collection
Cupro-nickel Coaxial Heat Exchanger (option) - Protects against corrosion when water conditions are of low quality
40A Non-fused disconnect (option) - Allows shut off of the unit without lockout of the main panel (N/A with electric heat)

Safety

Flow Proving Switch (option) - Prevents the operation of the compressor should the water supply fail
Unit Protection Module (UPM) - Monitors the unit operation and safety controls that protect the unit
Dual refrigerant sensors - Monitors refrigerant temperatures in the air and water coil to prevent freeze damage to the unit

Quality Design & Efficiency

Boilerless Control (option) - Disables the compressor and/or activates electric heater should the water temperature drop below adjustable set point
Extended Range (option) - Accommodates geothermal closed loop applications when Entering Fluid Temperatures are anticipated below 60 °F
TXV - Bi-flow thermal expansion valve for optimum performance over a wide range of heating and cooling conditions
Heat Recovery Package (option for 024-070 in -1 or -3 voltage only) - Provides domestic water heating during the air conditioning or heating mode to supplement your building's potable water heating needs assisting any electric domestic water heating storage tank
