The use of Danfoss TGE for R290 and R1270 in refrigeration plants is subject to explosion protection regulations for danger zone 2 (only rare or short term threat).

TGE complies with the requirements for explo-sive atmospheres (94/9/EC) ac. ATEX zone 2. TGE is marked with a label that indicates fire hazard (B.3.2 / ISO 3864).

TGE complies with the requirements in the Pressure Equipment Directive (PED) (97/23/ EC) fluid group I (flammable/toxic media). TGE is marked with a label that indicates fire hazard (B.3.2 / ISO 3864).

The Danfoss controls are, therefore, developed for this above-mentioned

requirement.

Only Danfoss valves and controls released for use with flammable hydrocarbons must be used with these substances. The actual me-dium must be stated in the product data sheet and / or on the product.

Only original Danfoss spare parts approved for use with flammable hydrocarbons must be used.

Technical safety require-ments

The refrigeration system must be located with-in the EU or EFTA and comply with the exist-ing EU legislation, such as the Pressure Equipment Directive (PED) (97/23/EC), the directive concerning potential explosive atmospheres (ATEX) (94/9/EC), EN 378, and other relevant EU legislation.

The refrigeration system must always comply with any local directive, legislation, and any other regulation applying in the area of installation.

Installation and mainte-nance

Only authorized persons, who are certified in installing and maintaining refrigeration plants containing flammable hydrocarbons, may do the installation and maintenance.

All requirements from local authorities, regard-ing use of hydrocarbons in refrigeration sys-tems, must be fulfilled.

The refrigeration system must be designed in such a way that no abnormal impact (e.g. abnormal vibration, liquid hammer, or pressure pulsations) can create risk for damage of the refrigeration system during operation.

Only original Danfoss spare parts approved for use with flammable hydrocarbons may be used.

The Danfoss products are classified accord-ing to the ATEX directive. Danfoss takes no responsibility for the classification of the refrig-eration system.
