Cold chain facilities usually use large amounts of refrigerant, so Danfoss has released the DGS gas sensor to combat the potential costs of refrigerant loss.
The Danfoss DGS is a gas detector which can detect a wide range of different gases.
The sensors can be used on a stand-alone basis or integrated into any refrigeration control system or building management system.
Typical refrigerant gas applications include all halocarbons – HFCs, HCFCs, CFCs – as well as carbon dioxide and hydrocarbons.
The cost of refrigerant loss is twofold: inherent cost to the business as well as the long-term cost to the environment. DGS is designed to offer customers the confidence that both safety and compliance requirements are met or exceeded.
Environmental requirements increasingly demand improved protection and responsibility of end users applying refrigerants in systems under their control. This has received growing support from governments with new laws and local regulations to ensure correct handling and responsibility.
The Danfoss GDS is available in IP41 and IP66 versions. Utilising either semiconductor (SC) or infrared (IR) technologies, DGS gives a quick and immediate response in detecting a wide range of different gases typically applied in refrigeration and air conditioning systems. DGS sensors can be used in stand-alone or integrated systems, where continuous, real-time, automatic monitoring with Danfoss Adap-Kool refrigeration control and monitoring system and/or building management systems are applied.
DGS supports Danfoss customers in complying with health and safety requirements on new or existing systems such as in supermarkets, process refrigeration plants, refrigerated storage and warehousing, special applications areas and zones.
Danfoss DGS gas sensors are essentially plug-and-play; if used as a stand-alone unit they can be simply wired up and, after a few minutes of the unit calibrating, are ready to go.
Despite this simplicity, the units have a number of features: visual and audible alarm via a red LED and audible buzzer that can be turned off if required; selectable fault state if connected to a monitoring system via analogue output; selectable time delays of 0, 1, 5, or 10 minutes can be selected; adjustable sensitivity with a simple adjustment from a refrigerant’s preset mid-point to anywhere between 1000 to 10,000ppm, based on requirements.
Versions are available immediately for R134A, R22, R404A, R507 and CO2.
