“DPWL” Leakage sensor

refrigerant gas leak detector
For the detection of CFC, HFC and CO2
refrigerant gases, CAREL proposes a new
range of sensors designed to satisfy all
requirements in the fields of industrial
refrigeration and air-conditioning
(supermarkets, shopping centres, other
public places) on units that require
continuous control and monitoring,
notifying system status in order to limit the
problems caused by gas leaks.
The sensors are calibrated to measure the
most commonly used gases (R22, R134a,
R404a, R407c, R410a and C02).
When leaks above a certain concentration
are detected, the sensor sends a signal to
the controller or supervisor it’s connected
to. The alarm is also signalled locally by
audible and visual indicators.

Preventing refrigerant gas leaks has the
following advantages:
• avoids system downtime or significant
economic damage due to poor food
storage, mean cost savings;
• contributes to reducing greenhouse gas
emissions, as established by the Kyoto
protocol;
• ensures surveillance over the safety of
people occupying the environment
where the refrigeration units are
operating.
Available in built-in or remote sensor.

• savings: a prompt
response avoids unit
downtime;
• safety: for people located
in the vicinity of the unit
and for food storage;
• signal: prompt warning
of system gas leaks

Installation of the gas leak detector ensures
compliance with European standards
F-GAS and EN378 as well as ASHRAE 15 (US
market).
