Automatic air purger GP2Improves performance and reduces operating costs of industrial ammonia refrigeration equipment
The presence of non-condensable gasses in the condenser leads to poorer heat transmission between refrigerant vapour and cooling water, and this reduces the condenser capacity.

Water, Dirt & Oil PurifierKeep your plant clean and save money
1% water content in ammonia
2% less cooling capacity
2% higher power consumption

SABROE CP Optimiser™Automatic device for balancing R717 condensing pressure against compressor efficiency
The CP Optimiser automatically calculates energy balancebetween compressor energy consumption and the energyrequired to reduce condensing pressure, taking intoaccount changing loads and conditions. This paves theway to considerable savings on energy bills, which meansthe CP Optimiser normally pays for itself within a matterof months.

5. Qualified Operation & Maintenance and using genuine spare parts
• Genuine parts result in lower energy consumption;
• Qualified service helps to maintain plant in optimal condition;
• Optimization of plant operation;
It is important to optimise the operation continuously, as this will secure that the
plant is adjusted to the optimal actual operation
conditions. This gives lowest possibly energy
consumption
