Reciprocating Scraped Surface Heat Exchangers − HRS Unicus Series

Reciprocating Scraped Surface Heat Exchangers − HRS Unicus Series

The design is based on a traditional shell and tube heat exchanger with scraping elements inside each tube. The reciprocating movement of the scrapers mix the fluid whilst cleaning the heat exchange surface. This keeps heat transfer high and reduces downtime. In addition, the scraping movements introduce turbulence in the fluid increasing levels of heat transfer.
This design makes the Unicus Series the ideal heat exchanger for applications where fouling or low heat transfer is a limiting factor. The Unicus Series can be applied in industrial and hygienic applications.
The gentle movement of the scrapers allows the system to be used with delicate products, such as whole fruit or vegetable pieces, without destroying the product integrity.
Rotating Scraped Surface Heat Exchangers − HRS R Series

Rotating Scraped Surface Heat Exchangers − HRS R Series

The HRS R Series is a scraped surface heat exchanger designed for the most difficult heat transfer applications, for example where very high viscosities and highly fouling fluids need heat treatment.
Unlike the HRS Unicus Series, where the scraper movement is reciprocal, the HRS R Series technology uses a rotary scraper rod. This scraper rod can reach velocities up to 300 rpm resulting in very high levels of shear and mixing at the heat transfer surface; dramatically increasing the heat transfer rate.
Plate Heat Exchangers, Gasketed

Plate Heat Exchangers, Gasketed

HRS Gasketed Plate Heat Exchangers are manufactured as standard from either AISI 304/316 stainless steel or titanium to a thickness of 0.6mm, although plate thickness options of 0.8mm or 1.0mm are also available if required. The exchangers are fitted with EPDM or NBR gaskets with the frames constructed from painted carbon steel. A double seal arrangement around the two ports ensures that if fluid leaks, it passes through the inter-space directly to the outside, avoiding cross contamination.
An extensive range of sizes of plate heat exchanger is available ranging from those models, which deliver flow rates of 0.7 litres per second to the largest units which are capable of flow rates of up to 819 litres per second (2,950,000 litres per hour). The range is designed for flexibility enabling the number of plates, the type and the number of flow paths to be varied, so that a heat exchanger can be manufactured according to a particular application in terms of power rating, operating temperature and pressure drop.
Plate Heat Exchangers, Brazed

Plate Heat Exchangers, Brazed

The HRS Brazed Plate Heat Exchanger range works on the same principle as conventional plate heat exchangers, but consists of a pack of corrugated plates joined together and sealed by furnace brazing.
Typically the units are copper brazed, however for applications where the medium is aggressive to copper, or for where temperatures range from 225°C to 400°C, then nickel is used. The plates are manufactured as standard from high-grade AISI 316 acid resistant steel with a thickness of either 0.35mm or 0.4mm dependent on the model type.
HRS brazed plate heat exchangers are suitable for heat recovery in the chemical, pharmaceutical, biotechnology and power generation industries, environmental processes and other industries.
Biogas Dehumidification System (BDS)

Biogas Dehumidification System (BDS)

The HRS Biogas Dehumidification System (BDS) removes water from biogas, protecting combined heat and power (CHP) engines from corrosion and cavitation. It can be supplied with a heat recovery section, increasing the overall efficiency of anaerobic digestion (AD) plants.
Concentration and Evaporation Systems

Concentration and Evaporation Systems

Evaporation is an efficient way of reducing the volume of effluents and wastes. Our evaporation systems raise effluent to its boiling point so that water is evaporated and then condensed, thus obtaining a concentrated end product and water. Forced recirculation uses a pump to send the product through the evaporator at high speeds, ensuring high velocity, good heat transfer and minimal fouling.
Where possible we aim to integrate our evaporation systems with waste heat sources to achieve an effective sustainable process.
Concentration of Environmental Waste for Renewable Energy (DCS)

Concentration of Environmental Waste for Renewable Energy (DCS)

The HRS Digestate Concentration System (DCS) reduces the volume of digestate from anaerobic digestion while increasing its value.
