CETCI Launches the DCC-MRI Oxygen Monitoring System

CETCI Launches the DCC-MRI Oxygen Monitoring System

Delta, British Columbia, Canada – Critical Environment Technologies Canada Inc. (CETCI) is pleased to tell you about the DCC-MRI Oxygen Monitoring System for MRI room applications in hospitals and clinics. The DCC-MRI replaces our GEM-MRI, offering technological and functional improvements over its predecessor.

Magnetic Resonance Imaging equipment is cooled by compressed gas. Compressed gas, if it leaks will displace Oxygen, creating the potential for an oxygen deficient or hazardous atmosphere. To meet general health and safety protocols, Oxygen monitoring devices are required to be present in MRI rooms. However, due to the strong magnetic field inside the MRI room, electronic equipment tends to not operate properly when mounted inside the room. The DCC-MRI system is designed to be installed on the wall outside of the MRI room with a flexible, sample line running from the inlet port fitting to the sampled environment. The factory tested maximum length of line is 15.24 m (50 ft). The DCC-MRI constantly monitors the target air area and indicates real time Oxygen levels on the LCD display.

The system is designed with an internal flow detector, sample draw pump, adjustable flow meter and an internal LPT-A Analog Transmitter that houses an integral Oxygen sensor. The measurement range of the sensor is 0 to 25.0% volume Oxygen. The alarm is factory configured to a descending alarm set point of 19.5% vol to alert if there is a deficiency of oxygen in the target air area.

Features include two 4 – 20 mA outputs, one alarm level line voltage relay with field configurable time delays and trigger levels, a blocked flow alarm indicating a dirty filter or clogged tubing, a side mounted audible buzzer, an LCD digital display with LED indicators for channel alarm status and fault conditions and a door mounted Silence push button.

The DCC-MRI Oxygen Monitoring System is designed to accurately measure to government established exposure levels for Oxygen deficiency for health and safety.

A Dual Channel Gas Detector for Monitoring Hazardous Gases in the Workplace

A Dual Channel Gas Detector for Monitoring Hazardous Gases in the Workplace

Critical Environment Technologies Canada Inc, (CETCI) offers strategic and reliable gas detection solutions for many applications. Our DCC Dual Channel Controller is an ideal fixed gas detection system for monitoring indoor air to protect workers from exposure to unhealthy levels of combustible, toxic and refrigerant gases, oxygen deficiency, and volatile organic compounds in the workplace.

The potential for exposure to hazardous gases is a concern in many workplace environments. In fact, every workplace must meet local (provincial/state, COOHS/OSHA, etc.) health and safety standards for hazardous gas exposure during working hours. To ensure the safety of the workers, equipment, and the facility, areas presenting a gas hazard should be monitored by gas detectors. In the larger, open areas, a fixed gas detection system is suitable; in confined spaces that workers enter and where gas may be present, portable gas detectors are more appropriate.

Commercial buildings that share a warehouse with manufacturing and/or service work in the back and offices in the front are a prime place for harmful gases and vapours to be present in the entire workplace area.  Airports, hotels, restaurants, supermarkets, shopping malls, manufacturing plants, food processing plants, vehicle repair shops, wineries, breweries and many more are all examples of workplaces where hazardous gases are used or produced onsite.

CETCI’s DCC Dual Channel Controller offers a fixed, continuous hazardous gas monitoring solution with two gas channels, two programmable relays, two 4-20 mA outputs and one configurable 4-20 mA input, an internal audible alarm, an LCD display with LED indicators and a password protected menu system. The two gas channels can be configured with one or two internal gas sensors, one internal and one remote gas sensor or one remote gas sensor, depending on the application requirements. The internal gas sensor options include toxic gases such as carbon monoxide, nitric oxide, nitrogen dioxide, oxygen, etc. The remote sensor options include refrigerants, TVOCs and combustible gases such as hydrogen, methane and propane. The DCC can also be connected to a remote 4-20 mA transmitter/gas detector such as our AST-IS (CO2), ART (IR refrigerants), LPT (CO or NO2) or LPT-A (various gases). All of our gas detectors come standard in a water/dust tight enclosure with a copper coated interior to reduce RF interference.

Optional, value added features for the DCC include an extra loud door mounted buzzer for noisy environments, a top mounted strobe, an internal heater for cold environment applications, and a door mounted water tight buzzer and splash guard for wet or spray down environments.

The DCC Dual Channel Controller conforms to CSA, UL, CE, FCC and IP54 standards.

CETCI Coats All Non-Metallic Enclosures to Eliminate EMI & RFI

CETCI Coats All Non-Metallic Enclosures to Eliminate EMI & RFI

Critical Environment Technologies Canada Inc. (CETCI) professionally coats the interior of all non-metallic system enclosures with a protective electromagnetic interference (EMI) coating for all their gas detection monitors and selective YES branded air quality instruments. This coating is designed to reduce or eliminate potential EMI and radio frequency interference (RFI).

For more than five years, CETCI has tested the EMI coating on the YESAIR. With good results, CETCI has decided to coat all their non-metallic enclosure products with the EMI coating. EMI / RFI shielding provides a high-level of protection without affecting the appearance or operation of the enclosure.

With the amount of electronic equipment being used nowadays, millions of waves and signals float through the air. Therefore, it’s important to protect the product from incorrect frequencies from interfering with the device. Applications, such as ambulance stations, may benefit the most from this as they have large transceivers and compressor / refrigeration rooms that use high voltage equipment.

Benefits to having a non-metallic enclosures includes reduced shipping cost due to the lighter weight of the product, easier installation due to being able to take apart the cover and base, reduced cost to produce a product resulting in savings passed onto the customers, and easier handling due to size and weight. With the many benefits of using non-metallic enclosures, CETCI feels that they are providing more value and a better product to their end users.

Self Contained Systems

Self Contained Systems

These products are systems that are called self contained because they include a controller and one or two sensors in one package. One of the sensors can be mounted integrally, both can be mounted remotely, or a combination. There is alarm indication at the controller for each channel and some units offer an optional digital display of concentration. Two relay outputs are included which are used to activate ventilation fans or remote alarm lights or horns.

These systems can be ordered set up for 24 VDC or VAC, 120 VAC or 220 VAC power supplies. Calibration and maintenance procedures are simple and can easily be performed in the field. Alarm setpoints are field adjustable. A full selection of sensors is available to detect a wide range of gases for a variety of applications.
