Sales stop of certain sizes of COOL DX/COOL DX Top

EU Regulation 2024/573 on fluorinated greenhouse gases tightens the requirements for which refrigerants may be used in refrigeration and heat pump products. For GOLD COOL DX and COOL DX Top, this means that certain sizes may no longer be placed on the EU market as of January 1, 2027.

Products subject to the ban: COOL DX Top size 005, 008 and 012 COOL DX sizes 008, 012, 020 and 030 in capacity variants 1 and 2

The last date for placing orders is therefore September 30, 2026.


The COOL DX/COOL DX chiller was originally designed as an integral component for GOLD air handling units. All the equipment is built into the unit, which you dock straight onto the GOLD unit or install as a stand-alone unit connected to the air handling unit.

COOL DX is based on a closed circuit filled with low-volume refrigerant. COOL DX provides cooling with a minimum of effort invested in planning, purchase specifications and installation.

The GOLD air handling unit has ready-to-use cooling functions for controlling and adjusting the COOL DX. This also includes communication via an online interface or with a master control and monitoring system.

COOL DX is available for end panel or top panel connection.
