The Macurco RD-6 is a low voltage, dual relay Refrigerant (REF) detector, controller and transducer. The RD-6 has select-able 4-20 mA output, buzzer and digital display options. It is an electronic detection system used to measure the concentration of refrigerant gas and provide feedback and automatic exhaust fan control to help reduce refrigerant gas concentrations in industrial refrigeration, cold storage or other commercial applications. The RD-6 is a low level meter capable of detecting several refrigerants including R-22, R-134A, R-404A, R-407C and R-410A.
A Macurco RD-6 is normally mounted low in the room on a wall or column one foot above the floor in a central area where air movement is generally good. Use the same spacing as for smoke detectors, 30-foot centers, 900 square feet per detector (84 sq. meters). The coverage depends on air movement within the room or facility. Extra detectors may be needed near any areas where people work or where the air is stagnant. The RD-6 mounts on a 4x4 electrical box supplied by the contractor. Do not install the RD-6 inside another box unless it has good air flow through it. Do NOT mount the RD-6 where the normal ambient temperature is below 0F or exceeds 125F (below -18C or above 52C).
