Contherm HP
Contherm® HP is a high-performance single-wall scraped surface heat exchanger (SSHE) designed for continuous and semi-continuous processing under extreme pressures. As the most robust model in the Contherm® family, it delivers superior durability and efficiency for industries handling high-viscosity products. Contherm® HP ensures optimal heat transfer and consistent product quality, whether for food, cosmetics, or industrial applications.
Unmatched performance under high pressure
- Withstands product pressures of up to 41.4 bar (600 PSI)
- Versatile solution that can handle particles up to 36 mm and viscosities well in excess of 50,000 cP.
- Fast and simple installation with self-aligning rotating shaft
- Easy-to-clean design can flexibly transition between products with limited downtime
- Robust construction ensures efficient heat transfer and reliable mechanical performance
For demanding applications, Contherm® HP offers twice the pressure resistance of a standard single-wall scraped-surface heat exchanger. Its advanced design eliminates the need for coupling components, integrating a self-aligning rotating shaft for seamless operation.
This innovation enhances reliability and minimizes maintenance, making Contherm® HP a preferred choice for industries requiring precision and durability. Like other Contherm® models, it can be installed vertically or horizontally, ensuring flexibility to meet space constraints.
Understanding the craped surface heat exchanger working principle
In a scraped-surface heat exchanger, product enters the cylinder from the bottom and moves upward, while a heating or cooling medium circulates in a counter-current flow through an annular channel.
Key Process Features:
- Rotating blades continuously scrape the cylinder wall, optimizing heat transfer.
- The product moves in a corkscrew motion, aligning with the rotating assembly to minimize shear and pressure drop.
- Adjustable product flow and rotor speed allow customization based on viscosity and process requirements.
This scraped wall heat exchanger design ensures uniform temperature control, preserving product integrity in sensitive applications.
More than you thought possible
For continuous processing of demanding products, the complete Contherm® range provides endless possibilities. In fact, today Alfa Laval is the only supplier on the market who can offer robust heat transfer with both double and single-wall scraped surface heat exchanger solutions.
We understand that no two customers’ needs are identical. That’s why Contherm® heat exchangers are always fully tailored to fit the intended application. The end result is more: more capacity, more efficiency and – most importantly – more profitability. When it comes to your business, who doesn’t want more?
Viscous products
The complete Contherm® range provides solutions for continuous processing of any type of challenging viscous liquid. Whether dealing with low or medium-viscosity products or those with extremely high viscosities, there is a member of the Contherm® family to fit your needs.
Example applications include: ketchup, mayonnaise, hummus, chocolate spreads, fruit pie fillings, gravies and sauces, whipped/aerated products, peanut butter, pizza sauces, puddings, salad dressings, salsa and taco fillings, sandwich spreads, bread dough, mechanically deboned meat (MDM), gelatine, omelettes, baby food, nougat, skin lotions, shampoos, liquorice, and more.
Heat-sensitive products
Scraped-surface heat exchangers are an ideal solution for heat-sensitive products that tend to cause fouling in other types of heat exchangers. With the most complete range available, Alfa Laval can support customers with any challenging heat-sensitive product need.
Example applications include: liquid and scrambled egg products, meat emulsions, fruit preparations and fruit purées, cream cheeses, whey proteins, and more.
Crystallizing products and applications with phase change challenges
Preserving taste, colour and/or texture is a particular challenge for manufacturers of products that can undergo crystallization. We work with your business to find the optimal Contherm® solution to fit your production.
Example applications include: coffee/tea extracts, icings and frostings, sugar concentrates, margarines, shortening, spreads, gelatine broth, lard, fondant, biscuit creams, solvents, fatty acids, petroleum jelly, beer and wine, and more.
Products with particulate matter
Contherm® solutions are always built to the specifications of the target duty. Whether you are processing products with large, small or mixed particles, or switching between non-particulate and particulate products, your Contherm® can be adapted to meet the demands.
Example applications include: meat, chicken pieces, fish meal, pet food, jams and preserves, yoghurt with fruits, a variety of fruit preparations, rice pudding, vegetable pieces, and more.
Sticky products
Many heat exchangers encounter limits when handling process fluids that are sticky. For Contherm®, however, it’s never a problem. The complete Contherm® family can support a full range of mildly to extremely sticky products, from foods to beauty products and more.
Example applications include: caramel, cheese sauces, lecithin, processed cheese, confectionery, yeast extracts, gums, gelatine, mascara, toothpaste, starch, and more.
