Insulation for Cold Systems

SUM Anti-freeze Guard covers are designed to meet the specific requirements of refrigeration systems such as ammonia, glycol and chilled water circuits. These covers eliminate condensation and ice build-up, which commonly occurs on uninsulated valve components. They significantly reduce downtime during maintenance operations (no ice formation on valves) and improve the energy efficiency of distribution systems.
  • Compressors
  • Process cooling storage systems
  • Pumps and heat exchangers
  • Instrumentation and control equipment
  • Process temperature stabilisation
  • Complete pipework systems

SUM Anti-freeze Guard covers offer high resistance to water and water vapour. They are suitable for industrial valves operating at low temperatures, such as chilled water or ammonia systems. They reduce losses of process cooling capacity caused by unwanted heat gain in the working medium. They also limit ice build-up on valves.

At the same time, they provide quick and easy access to insulated equipment thanks to simple, tool-free operation.

Designed for repeated use, they can be removed and reinstalled without damage.

Inner and outer technical fabric layers – a wide range of glass fabrics is available in different impregnation and coating variants (silicone, PTFE, PU, aluminium, etc.). The selection of the appropriate fabric for a given application is determined by the temperature and operating conditions of the installation.

Insulation fill – in 80% of products, mechanically needled E-Glass glass fibre matting is used, which, unlike standard mineral wools, is characterised by:

  • high density: 130 to 180 kg/m³
  • water resistance – even after full saturation, once dried it regains 100% of its insulating properties
  • durability and structural integrity – it does not deform under bending and does not delaminate or fragment

Other materials used include silicate mats, synthetic rubber, Pyrogel and others.

The fastening and closure systems are always adapted to the specific application, taking into account temperature conditions, surrounding equipment layout and individual user requirements. Industrial Velcro (including high-temperature variants), stainless steel buckle straps (standard), drawstring cords and stainless steel hooks are used.

Nameplate – each cover is assigned a unique serial number, and its design is stored indefinitely in the SUM database. The nameplate may also include any user-required information (location, equipment identification, etc.).

All fittings in every version of the SUM cover are made of stainless steel.

Extremely strong seams made from stainless steel-reinforced Kevlar®-wrapped thread ensure long service life and high thermal resistance.
