SCRAPED SURFACE HEAT EXCHANGER

Light and medium duty heat exchanger

scraped_surface_heat_exchanger

Specifications
Field of application Dairy and food industries

Description Vertical cylinder arrangement mounted on a base console with gear motor. The dasher top bearing is inside the product area, whilst the gear motor supports the dasher bottom. This means that there is only one shaft seal for each SSHE cylinder.
Heat transfer surfaces:
Cylinder size 422: 0.19 m² (2.1 ft²)
Cylinder size 460: 0.44 m² (4.7 ft²)
Cylinder size 660: 0.68 m² (7.3 ft²)
Cylinder size 680: 0.87 m² (9.4 ft²)

Capacity Dependent upon product and application, but typically up to 3,000 or 5,000 kg/h (6.600 – 11.000 lbs/h)

Temperature Working temperature up to 150°C (300°F)

Advantages

Best solution for treatment of viscous and heat-sensitive products
Capable of handling products with large particles
Long running time between CIP when processing heat-sensitive products
Suitable for aseptic operation
EHEDG-tested and approved

Heavy-duty (HD) and heavy-duty extra (HEX) heat exchanger

Specifications

Field of application Heating, cooling, crystallising and freezing in the dairy, food and other process industries

Description HDRT and HEXRT heat exchangers are designed to handle highviscosity products in heating, cooling, crystallising and freezing applications. They feature a horizontal cylinder arrangement based on a
rigid construction with demountable cylinder end doors and strong
bearings outside the product area to support each dasher end. The RT appellation means that the gear motor is flanged direct on to the SSHE cylinder module.
Heat transfer surfaces:
Cylinder size 648: 0.55 m² (5.9 ft²)
Cylinder size 672: 0.84 m² (9.0 ft²)
Capacity Dependent on product and application,
but typically up to 3,000 or
5,000 kg/h (6,600 – 11,000 lbs/h)
Temperature Working temperature up to 150°C (300°F)

Advantages

High-precision machined and polished Duplex quality and Bimetal cylinders
Also suitable for evaporative refrigerants (R717 and R404a etc.)
Product pressure up to 30 bar (435 Psi)
Various dasher diameters, scraper blade types and configurations, as well as
powerful dasher motors

Light and medium duty SSHE

Specifications
Field of application Dairy and food industries

Description Horizontal cylinder arrangement mounted on a frame. The dasher is supported in both ends outside the product area, which makes the dasher pressure balanced. The heat exchanger type HT 680 is designed according to the EHEDG and 3A requirements. Approval is still pending.
Heat transfer surface: 0.87 m² (9.4 ft²)
Capacity Up to 3,000 or 5,000 l/h (6,600 –11,000 lbs/h) depending on duty and temperature
Temperature 150°C (300ºF)

Advantages

Shaft seals are standard APV pump type for easy maintenance.
Product and service connections do not need to be disconnected for maintenance.
