Basic items to increase Energy Efficiency 1. Proper design of refrigeration system; 2. Using modern and reliable refrigeration equipment; 3. Utilization of Heat Recovery Solutions. 4. Additional Value Engineering Products 5. Qualified Operation & Maintenance and using genuine spare parts;
1. Refrigeration System Design Energy optimization Rules of thumb 1K lower evaporating temperature 1K higher condensing temperature 5 to 8% less cooling capacity 3% lower COP 1% less cooling capacity 3% higher power consumption
2. Using modern and reliable refrigeration equipment; SABROE products line card SMC 100 CMO 20-30 HPC 100 HPO 20 HPX 700 SAB screw small SAB screw large SABflex HP Screw 40 HP Screw 60 ChillPAC ComPAC PAC chiller recip PAC screw Air cooled chiller CAFP HeatPAC Heat Pumps DualPAC Unisab III CPC Panels ISAC
SMC reciprocating compressor Through comprehensive development we introduce the SMC MK4LL Meets customer demands for performance extended service life (12.500 hours @-10/35 0 C) Load based service intervals (optional) Skip-free design reduced oil carry over (10 ppm guaranteed) small footprint Developed for variable speed Skip-free speed regulation 500-1800 rpm 100% to 27% capacity without mechanical unloading

ComPAC - Built for high efficiency ChillPAC is Superior in terms of refrigerant charge footprint simplicity performance optional equipment. ChillPAC meets customer demands for performance small footprint /compactness low noise competitive price ChillPAC exceeds customer expectations regarding local or remote condenser chiller control, Unisab III VSD solution small refrigerant charge economiser for low-temperature applications Core values from ChillPAC Screw based Chiller solution Higher capacity >2 MW Wide range of options including posibility for adding Economizer
Reciprocating part load optimization VSD Unloading of cylinders 30% part load 43% higher efficiency 60% part load 13 % higher efficiency
Screw part load optimization VSD 30% part load 60% part load 12% higher efficiency Capacity slide 40% higher efficiency
Part load efficiency for both recip and screw units Screw VSD / Recip VSD 30% part load 25% higher efficiency using recip VSD Screw VSD / Recip VSD 60% part load 7,5% higher efficiency using recip VSD
3. Heat Recovery Solutions Using Desuperheaters for hot water production; Using Heat Recovery Solution for compressor oil cooling Heat Pump Solution
Heat Recovery - Desuperheater
Heat Pump Solution Heat energy sourced from cooling tower / dry cooler using heat rejection from existing refrigeration plant Cascade exchanger system Remember: Additional savings on water consumption and fan power
Use The Energy Twice Heat Pump Solution
4. Some Additional Value Engineering Products Economizer Air Purger Water, Dirt and Oil Purifier (WDO Unit) Condenser Pressure Optimizer (CPO)
Economizer Optional adding Economizer 16.0% Efficiency Gain w/ Economizing - Adds value at large differential pressures - Frequently used for low temperature applications - Considerable increased capacity - Significant improved efficiency 14.0% 12.0% 10.0% 8.0% 6.0% 4.0% 2.0% 0.0% -60-40 -20 0 20 40 60 Evap Temp (F) NH3
Automatic air purger GP2 Improves 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 Purifier Keep 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 balance between compressor energy consumption and the energy required to reduce condensing pressure, taking into account changing loads and conditions. This paves the way to considerable savings on energy bills, which means the CP Optimiser normally pays for itself within a matter of 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
