Güntner


Güntner’s Communication Modules are available for Güntner Motor Management (GMM) and Güntner Hydro Management (GHM)controllers, complemented by in-house developed industrial Ethernet communication protocols.


The GCM WiFi Module connects the control unit Güntner Motor GMM EC to a WiFi or LAN network. The control unit allows for reading individual parameters from the control unit and for changing parameters. Thanks to our development and introduction of the BACnet/IP and Modbus/TCP communication protocols, the WiFi Modules for the GMM and GHM controllers meet all of today’s refrigeration engineering requirements. The previous functions of the GCM WiFi Module are also available when using the BACnet/IP and Modbus/TCP communication protocols.


Unit information and settings are accessible via an app, web browser or remote access when connected via a VPN tunnel. www.guentner.eu

J&E Hall


J&E Hall has extended its range of digital single scroll commercial condensing units. The new V3 digital scroll condensing units, aimed at the small cold store, convenience store and restaurant markets, are now off ered in four, six and eight horsepower models with improved features.


Electronic controls optimise the operation of the units by varying the capacity with the digital compressor. Hinged doors have been added to improve access, and additional isolation valves make it easier for engineers during servicing and maintenance. The controller program has also been updated to include communication with third party controls. The units, designed for medium temperature applications, can operate with the lower GWP refrigerants R448A and R449A as well as R404A, R407A and R407F. They are also compliant with EU Ecodesign legislation. With capacities up to 24kW and evaporation temperature ranges between -20°C and 10°C, the units are especially suitable for multi-evaporator systems. The condensing units come fi tted as standard with an oil separator for additional compressor protection and are acoustically lined for reduced noise levels. J&E Hall also off ers the digital twin scroll commercial condensing unit with a capacity up to 38kW.
