QD-REF Series - Quadset Refrigerant Gas Monitor

The Acme Quadset Refrigerant Gas Monitor is designed to detect refrigerant leaks in enclosed areas. The Monitor utilizes a sophisticated NDIR sensor specific to any one of the commercially available refrigerants. It can monitor over a range of 0-1000ppm with a resolution threshold as low as 1ppm.

Applications

Suitable for control of emergency ventilation systems and for personnel protection
Refrigerant leak or spill detection from chillers, pipes, compressors and valves
Commercial or industrial facilities using chillers or refrigeration units, food plants, meat-packing plants and cryogenic plants
Direct connection to the existing building management system
(BMS) or DDCS

The Quadset can monitor up to four locations in one of two modes of operation, diffusion or sample-draw.

In the diffusion mode, up to four RF-IR-ST-24 Refrigerant Sensor/ Transmitters can be daisy-chained to the Monitor and transmit data on a RS-485 communication bus.

In the sample-draw mode, built-in diaphragm pumps continuously draw air samples from the four locations via tubing, the incoming samples are then diverted to a built-in sensor by means of a sequencer and solenoid valves.

The Quadset is easy to install and maintain. It has a 4-line backlit LCD for refrigerant gas readings and LED indicators for relay output status. The LCD is also used for programming the system parameters via a removable keypad.

Designed to act as a fixed in-situ safety monitor, the Quadset automatically operates the mechanical ventilation system of a facility upon detection of low levels of refrigerants, thereby protecting occupants, personnel and gas-sensitive goods and products.

The standard Monitor has a 3-stage relay output configuration and a malfunction relay. Options include 4-20mA analog output based on average or worst reading, a strobe light and/or a horn.

With the increased use of gas detection in maintenance and industrial facilities, the Quadset allows installers and users to meet code requirements in an economical fashion using commercial-grade gas detection equipment.

The Quadset contains all the well-known standard features of ACME’s gas detection line; a robust enclosure, the latest sensor technology and state of-the-art electronics. For more versatile gas options, please consult the ACME binder or website.
