The ‘PB’ (potable bakery) range of water chillers is designed to chill a specified volume of mains water to a temperature close to zero, prior to being used as part of a food mix.
There are twelve models in the range able to chill water to 5°C or less without the use of glycol. The unique design of evaporator coil, being a series of tubes formed into a number of parallel circuits, provide the surface area for the heat transfer from refrigerant to water which is unaffected by water circulation volumes.
Water is taken off town’s mains supply and measured into holding tank, where it is agitated and chilled as it comes into contact with the cold evaporator surfaces. Agitation on the small units is generated from high water circulation rates, off process pump which run continuously to ensure water does not rest in external pipework and gain heat from ambient. Larger units are fitted with an additional agitator system. As water is drawn off ring main to mixers more mains water is added to the bulk holding tank via a solenoid valve actuated by level switches within the tank.
Options available specifically for PB range:
• 316 stainless steel evaporator coil
• 316 stainless steel tank
• 316 stainless steel pipework
• Split system (tank/evaporator alongside refrigerant condenser)
• Twin pump system
• Dual systems incorporating common tank
• Weatherproofing/frost protection
• Remote control
• Special electrical circuits
