Temperature control units with up to 150 g natural refrigerant
▪ The temperature control unit has been constructed to the requirements of EU and EFTA coun-
tries.
▪ Use the table as guidance for classifying the application field. Respect the max. refrigerant quanti-
ty stated therein.
Temperature control units with more than 150 g natural refrigerant
▪ The temperature control unit has been constructed to the requirements of EU and EFTA coun-
tries.
▪ Use the table as guidance for classifying the application field. Respect the max. refrigerant quanti-
ty or the permissible highest quantity above ground level (GL) stated therein.
▪ For more information about the pre-installed gas detection sensor:
- The built-in gas detection sensor enables a safety shutdown at 20% of the lower explosive
limit via a power disconnect relay that is to be installed by the responsible body. The
temperature control unit is thus switched off early and safely in case of fault.
- A 24 V DC external power supply must be available for the pre-installed gas warning sen-
sor. The alarm output of the gas warning sensor uses a 4 - 20 mA signal. Please refer to the
data sheet of the gas warning sensor for further technical information. A separate pro-
cessing unit is available as an accessory for the control of the power disconnect relay. The
processing unit provides a potential-free switching contact and simultaneously provides
the power supply and analysis of the gas warning sensor. Both variants require the respon-
sible body to provide the necessary dimensioning and installation. Please refer to the data
sheet of the gas warning sensor for the technical information necessary for the installa-
tion. The alarm of the gas detection system can be connected to the responsible body’s
alarm control unit. The responsible body is responsible for this and for the other measures.
- The responsible body is responsible for the calibration of the gas detection sensor prior to
initial operation and the observance of calibration and maintenance intervals according to
the operating manual. We recommend to set calibration and maintenance intervals be-
tween 6 and 12 months if no information is provided. For increased safety requirements,
shorter intervals can be specified. On request we will recommend a specialist company to
carry out the calibration and maintenance.
1.3.1.2 Temperature control devices with fluorinated greenhouse gases/refrigerants
F gases regulation (EC) No. 517/2014 of April 16, 2014, on fluorinated greenhouse gases, and re-
pealing Regulation (EC) No. 842/2006.
These regulations deal with all systems that contain fluorinated refrigerants. The substances dealt
with in Directive (EC) No. 1005/2009 of the European Parliament and of the Council of 16 September
2009 that deplete the ozone layer are excluded (CFC/HCFC).
The directive regulates the reduction of the emission, utilization, recovery, and destruction of cer-
tain fluorinated greenhouse gases. It also regulates the identification and disposal of products and
devices that contain these gases. Since July 4, 2007, responsible bodies must check their stationary
refrigeration systems for leaks at regular intervals, and have any leaks eliminated immediately.
Directive (EC) No. 303/2008 contains stipulations on the training and certification of companies and
personnel that are permitted to execute the specified activities.
Obligations of the responsible bodies:
▪ Directive (EC) No. 842/2006 already imposed a number of obligations upon responsible bodies
regarding certain fluorinated greenhouse gases. The new Ordinance on Fluorinated Greenhouse
Gases upholds these to a large extent. Some duties are added while others are designed different-
ly by this new ordinance. Please refer to the text of this ordinance for a complete overview of the
individual responsible bodies.
▪ General obligation to reduce emissions.
▪ Only certified companies may maintain, repair or decommission refrigeration systems. The re-
sponsible bodies must verify that these companies are certified.
▪ Until 31.12.2016: Annual leak tests of stationary refrigeration systems by certified personnel
(such as service engineers of Peter Huber Kältemaschinenbau GmbH). Valid for a filling capacity of
6 kg to 30 kg of fluorinated greenhouse gases.
