Alco Controls EPR-14 Evaporator Pressure Regulator

The Alco Controls EPR-14 Evaporator Pressure Regulator is a refrigeration-control valve designed to maintain evaporator pressure at a preset level when multiple evaporators share a common suction line. By stabilizing evaporator pressure, it helps prevent frost formation in low-load conditions and supports consistent cooling performance as system demand changes. This model is part of Alco Controls’ evaporator pressure regulator family, a category described in their literature as regulators that hold evaporating pressure above determined setpoints to manage rack-wide suction pressure. In typical installations, an evaporator pressure regulator is positioned in the evaporator inlet or on the suction-line circuit to modulate flow in response to pressure fluctuations, contributing to more predictable system behavior and, in some configurations, aiding oil return. When selecting an EPR-14, it is essential to consult the official Alco Controls catalog or datasheet for exact installation details, including setpoint range, connection size, and mounting configuration appropriate to your refrigerant and rack layout.
