1 Degree Water Chiller

High Efficiency Chiller Heater

1°C GLYCOL FREE ABSORPTION MILK CHILLER

• To overcome all the detrimental effects of PG use, Thermax has introduced a series of chillers which can give 1oC chilled water outlet temperature.

• Sufficient care has been taken in the design to avoid freezing of water.

• As pure water is being used, optimum HTCs are observed in the chiller and cost/ TR reduces.

• Also, , the recurring costs of glycol maintenance is avoided

• The pumping power requirement will also reduce

1oC Chiller : Glycol Free Operation

• To overcome all the energy losses of conventional IBT system, Thermax has introduced a series of chillers which can give 1oC chilled water outlet temperature.

• Since open Ice bank system were used there are lot of losses energy and the compressor were running continuously consuming lot of electrical energy.

• With 1oC water Chiller we can reduce these losses as the water can go directly to the PHE for milk chilling or through closed Hot/cold well circuit.

1oC Chiller : Reduce energy losses of IBT System

• At Lower Chilled water outlet temperatures, LiBr is added to the refrigerant circuit to avoid freezing

• The amount of LiBr to be added to the refrigerant circuit is governed by depression in freezing point desired.

• LiBr amount added is continuously monitored and maintained during chiller operation to ensure efficient running

• SS tubes are used in the Evaporator

• Chilled water flow meter is included as a standard feature

• The flow meter is used to monitor & control flow velocity in the tubes, the flow is not allowed to go below 60% of rated flow there by maintaining minimum velocity of water in tubes

High Efficiency Chiller Heater - Features• Chiller and heater circuit are conjoined in a way that both are made mutually

interdependent.

• Easy controllability of vapor flow during various load conditions.

• Reduced Energy consumptions like Gas / oil /Steam etc, 40 % reduction in Heating energy

• Reduction in CO2 emission.

• Heat rejection to cooling water is reduced results in reduction in make-up water required for cooling tower

• As Chiller heaters use latent heat of refrigerant vapour, 75% of chilling capacity can be attained as heating duty, as against electric chillers which use sensible heat due to which only ~8-10% of chilling duty can be provided as heating duty.

High Efficiency Chiller Heater - Applications• Dairy• Cooling – Milk chilling• Heating – Pasteurization

• Breweries• Cooling – Wort cooling• Heating - Sparging

• Coffee processing• Cooling – Air conditioning, Agglomerator• Heating - Dehumidification

• Tea processing• Edible oil• Malt processing• Minerals & metals
