Gas detectors for Industrial Refrigeration: Safety, efficiency and peace of mind

Transcription

1 Gas detectors for Industrial Refrigeration: Safety, efficiency and peace of mind Gas detectors from Danfoss are designed to meet the requirements of every industrial refrigeration application you can think of, regardless of refrigerant type, measuring range or sensitivity. Designed for stand-alone use or as part of a multiple detection system. Dedicated gas detection program for industrial refrigeration

2 Reliable, real-time monitoring of your industrial refrigeration system Gas detection in industrial refrigeration is becoming increasingly vital in today s production environment. Protecting people, goods and expensive equipment is a pressing concern when designing and operating large-scale refrigeration systems. Added to that are the ever-increasing demands for preserving the environment from the leakage of gases such as HCFC/HFC not to mention the fact that such gases are quite costly in themselves, and an undetected leakage can run up your costs quickly and substantially. Main product features: Full compliance with all relevant regulations, national or international Available for all commonly used industrial refrigerants including ammonia (NH3), CO2, HCFC/HFC and HC Available with four different sensor types: Infrared, electro-chemical, semiconductor and catalytic The sensors incorporate an interchangeable pre-calibrated sensor board, which makes it very easy to replace the sensor without expert knowledge of gas detection and calibration Alarm levels and delays can be set to suit your requirements A well-designed gas detection system lets you monitor your entire refrigeration system, either as a total perimeter control system or as a single-point detection safeguard, e.g. next to compressors or other sensitive equipment. Your one-stop shop for gas detection Danfoss gas detectors comply with all local and international regulation and are engineered to meet all industrial refrigeration applications Linear output proportional to the gas concentration. Outputs: 0-5V, 0-10V, 4-20 ma and two digital dry contacts Built-in RS485 bus communication system allows for interface with Danfoss SM 350 monitoring unit Optional display: LCD display, IP66 enclosure and EExd (explosionproof) Danfoss gas detection sensors can function independently as standalone units with an interface to PLC systems Up to 99 gas detection sensors can be connected to the Danfoss SM 350 monitoring unit requirements, from vessel engine rooms to large-scale industrial refrigeration plants. We supply you with not just the gas detector units themselves we can also supply everything from spare parts to monitoring units, making it possible for you to design a complete gas detection system using only trusted Danfoss parts and knowhow. You can also rely on Danfoss to provide firstclass servicing and customer support, wherever you are. Your direct benefits: Early gas leakage warnings will increase safety and reduce costs from leaks Dedicated gas detection program for industrial refrigeration Wide range of approvals and certificates Tried and tested Danfoss quality in every component One-stop shop: Just one global supplier for all your refrigeration needs Easy and fast replacement of sensor PCBs for different gasses, detection ranges etc. Applications: Danfoss gas detectors are particularly well suited for marine applications, compressor machinery rooms, cold stores, distribution centers and general industrial buildings.

5 Safety on board guaranteed by Danfoss gas detectors At sea, safety comes first. Once out of the harbor, a vessel is pretty much left to its own devices, and help can be hours, maybe days, away. Naturally, the focus is on preventing accidents from happening, and therefore vessel construction and operation always rely on suppliers and equipment which are best in their class. Havyard MMC Refrigeration offers refrigeration solutions for marine applications such as marine RSW systems, freezing systems, compressor units and air-conditioning and Havyard, of course, has chosen Danfoss as its supplier for gas detectors on board vessels. Recently, Havyard has fitted two passenger ferries with gas detectors from Danfoss to be used in cargo holds, freezing rooms and compressor rooms close to each cargo room and AC compressors. The onboard systems all use Freon (R 427A) as a refrigerant. The semiconductor detection devices from Danfoss help safeguard the environment for crew and passengers and will also help reduce cost by the early detection of gas and refrigerant leakages.» For us, Danfoss is more than a supplier we see Danfoss as a partner. At Havyard MMC, we have worked with Danfoss for more than twenty years. With their wide range of high-quality products, excellent technical support organization and short delivery times, there s just no other supplier out there like Danfoss.«Torje Berger-Hanssen Sales Manager Havyard MMC Refrigeration AS
