QUICK RESPONSE EXPANSION VALVEAND PRECISION SUPERHEAT CONTROLLER SELECTION GUIDES

* Nominal Capacity Rating for each refrigerant type is based upon vapor free, 38°C (100°F) liquid efrigerant entering the expansion valve with subcooling of 2°F, evaporator temperature of 4°C (40°F with superheat of 4°F), and no pressure loss in the copper line.

NOTE: Add -C to the end of the model number for single pack.

Control what’s important.

QUICK RESPONSE EXPANSION VALVE

• MEMS based hybrid expansion valve for refrigeration and HVAC applications

• Compact footprint

• PWM signal control with quick response time (0.25 second for full stroke)

• Valve is refrigerant neutral (each valve can be used with any of 17 approved refrigerants)

• Direct TXV or EEV replacement

PRECISION SUPERHEAT CONTROLLER

• Precise superheat control

• Closed loop control

• Internal MEMS suction pressure sensor

• External temperature sensor

• Built in PWM driver

• Multiple refrigerant database: controls any one of 17 approved refrigerants

• Communication: RS485 serial bus with Modbus RTU protocol

BENEFITS

• Fast, accurate control of refrigerant flow and superheat for maximum evaporator efficiency

• Silicon-based MEMS technology eliminates valve wear, extending life: no stepper motor failures

• Preconfigured PSHC reduces install and commissioning time

• Closed loop solution: no front-end controllers needed

• ModBus RTU: integrate into popular refrigeration control systems for remote visibility

• Power failure: valve closes with loss of power, protecting compressor from refrigerant flood back

• High durability, reliability

• Backed by a 3-year warranty

Introducing the new Quick Response Expansion Valve (QREV) and Precision SuperHeat Controller (PSHC) – a closed loop solution

from PENN. Together, the QREV with the PSHC kit forms an electronically controlled expansion valve that will maximize evaporator

efficiency. It allows users to capture energy savings by reaching targeted superheat faster and controlling the valve more precisely,

through varying load conditions. This unique silicon-based MEMS technology eliminates valve wear. There are no stepper motor

failures associated with this type of technology. The PSHC comes loaded with any one of 17 approved refrigerants for easy

commissioning, plus it has an on-board pressure sensor. The wiring harness, which completes the kit, includes a temperature

sensor. This new product combination is easy to install, precise, fast and reliable. Just what you would expect from PENN.
