GEA
STAND NUMBER 187
AS OUR PLANET gets hotter, com- panies all over the world are looking for better ways to reduce their carbon footprint and optimise their energy efficiency. At GEA, we can help our customers achieve just that because we’re in the privileged position of be- ing able to develop sustainable cool- ing and heating solutions under one roof thereby accelerating the decar- bonisation transition.
The GEA solution encompasses:
• Grasso reciprocating compressors/
compressor packages.
• Grasso screw compressors/screw
compressor packages.
• Grasso “Blu” series of chillers en-
compassing screw/reciprocating compressors for indoor/outdoor applications.
iZone
THANKS TO THE emergence of smart technol- ogy, climate control systems have come a long way, but not all systems are created equal. Regulating a home’s heating and cooling with maximum efficiency and minimal costs, all de- pends on the level of control engineered into the system. With greater control comes increased comfort, lower running costs and an extremely secure system.
The key to greater security of in- ternet connected systems lies in iZone’s uniquely embedded firm- ware and system design features.
FLOATING SENSOR
A system with a floating sensor is the most efficient way of controlling different temperatures in different
zones. The f loating sensor constant- ly monitors all the sensors in the home to see which sensor should be the controlling sensor. As the tem- peratures in zones change so does the controlling sensor hop from zone to zone. Once zone setpoints
• Grasso “Red” series of heat pumps for water/water & water/nh3 appli- cations delivering water up to +95 degrees celsius.
• Grasso customised heat pump solutions.
• Omni Control panels.
• GORP Field retrofit control panels. • PR-OLEO oils.
The GEA solution is suitable for beverage, chemical, cold storage / lo- gistics, dairy, dairy farming, food manufacturing, heating & refrigera- tion, marine, oil, gas & energy and pharmaceutical & healthcare.

have been reached, any excess air is bypassed into the return air bypass damper, helping the system to cycle more effectively.
IN-DUCT SUPPLY AIR SENSOR
Having an in-duct supply air sensor adds anoth- er level of control and efficiency. Installing this into the path of the fan coil in the supply air starter will allow the temperature of the air in the duct to be measured. This then allows a zone damper to open, so any remaining hot or cold air in the supply air duct can be used, rather than having to restart the machine.
BYPASS DAMPER
Comfort and control can be greatly improved through having a bypass damper. As zone tem-
peratures reach their desired set points, any ex- cess air in the system will automatically divert into the bypass damper system and directly into the return duct in the roof cavity, thereby not af- fecting the perfect temperature achieved in the conditioned space. Once the bypass becomes active, the unit can then start to go through its own control sequence and wind back the out- door compressor.
AUTO FAN CONTROL
This is a feature which allows the system’s fan speed to automatically adjust according to how many zones or rooms are being heated or cooled. Only the optimal amount of air flow will be travelling down the duct into the zone, helping to reduce running costs with no
manual intervention required.
ECONOMY MODE
Economy mode is an important fea- ture that will help achieve optimal efficiency and to further save on en- ergy costs. A user can set the upper and lower temperatures so that the system only ever operates between these two temperatures regardless of what is input at the time.
The best climate control systems should be capable of delivering pre- cise climate control, greater energy efficiency and improved comfort all year round.
