Kelvion air cooler ceiling / wall commercial SGA 23-F21

Kelvion SG commercial

The requirements for components in complex cooling and refrigeration systems are just as demanding. Kelvion has thoroughly re-engineered its high-performance SG commercial cooling and further optimised how the components work together.
Energy efficiency has been significantly increased. Kelvion is actively providing a sustainable solution to constantly increasing operating costs and consistently implementing the ever more stringent regulations.

Whether for extreme storage conditions or for reliably ensuring long-term freshness - the SG commercial guarantees the required process reliability to maintain the quality of your refrigerated products as well as provide long-term investment security.
Our design focus is oriented around your requirements and is based upon: long periods of cooling between defrosting processes, low power consumption by the fans and good control characteristics with minimal temperature differences. This results in the compressor requiring a minimal amount of power to achieve the required cooling capacity.

MAXIMUM ENERGY-EFFICIENCY
Aerodynamically integrated fan system with air flow control. The benefits for cold storage areas: A strong, bundled flow of air with more volume and greater range.
Thanks to the optimum fin structure of the Küba-HFE® system, the optimised design of the heat exchanger allows stable regulation with minimal temperature differences, even when under partial load.
The EC fans reduce energy consumption by up to 67% (average approx. 30%). The fan unit can also be swivelled (except for SG 23), heated and has a new condensate return.

ABSOLUTELY HYGIENIC
All parts are easy to access and easy to clean.
The foldable tray and swivelling fans (except for SG 23) are standard features.
The parts that make up the housing have a food-safe and environmentally friendly powder coating for a surface that is resistant to scratches, impacts and corrosion as well as being easy to clean.
The air flow control system is easily removed for easy cleaning.
A condensate drainage channel is integrated into the fill nozzle: Reliable drainage of condensation.

SIMPLE INSTALLATION
The integrated terminal box (except for SG 23) with sprint-type terminals as standard allows quick and secure connections.
The generously proportioned connection areas allow for easy handling. This is particularly the case for the refrigerant pipe connection and expansion valve installation.

The rounded corners and deburred edges of the housing components means that there is no danger of injury to installers and cleaners.

BEST PROTECTION FOR YOUR GOODS
≤ 15% output range with lower air resistance and larger air volume: The new fan system with air flow control has been precisely adapted to the heat exchanger.
The large number of different variations and options means that the SG commercial can be specified to precisely meet your individual needs - even in complex cooling applications.
The latest technologies and excellent heat transfer ensure minimal temperature differences. The optimum configuration of the air cooler is key to ensuring a minimal dehumidifying effect.
