SIHI hot oil and hot water heat transfer pumps from RuhRPump SIHI Australia have been specially developed for handling heat transfer liquids and media, such as mineral and synthetic heat transfer oils.
In temperatures ranging up to 200°C, water is the preferred heat transfer medium as it is non-polluting and has a high specific thermal capacity. In temperatures ranging from 200°C to 400°C, organic heat transfer liquids are preferred. This is because vapour pressure also rises considerably when temperatures increase.
SIHI Hot Oil heat transfer pumps may be used in installations with positive or negative suction pressure, and are primarily used in industries and applications such as:
- plants of the chemical industry - heating of agitators, reactors, drying plants, polymerisation plants, plants for conveying high-viscous products and producing plastic materials and synthetic fibres
- rubber and plastic industry - heating of calendars, melting pots, power presses for plastics, automatic injection moulding machines, production of PVC adhesive tape
- food industry - heating of baking and fish-frying ovens, distillation of fatty acids and glycerine, fat softening plants, production of potato chips and milk powder
- paper industry and laundries - calendar rolls, production of corrugated cardboard, heating of washing machines, mangles and dryers.
Fields of application for SIHI Hot Water heat transfer pumps include energy production and heat transport industries, and mainly in systems where hot water is given preference as a heat carrier.
