Thermal Insulation with Heating Installation – with an active system for protection against crystallisation and freezing

SUM Heating Guard covers are not only passive insulation but a complete protection system against crystallisation and freezing. The heating cable is integrated into the inner layer of the cover, while an external electronic thermostat with a power cable is installed on the outside – providing a ready-to-use plug-and-play system.

  • Systems with crystallising media such as paraffin, chocolate or water
  • Valves, filters and flanged connections
  • Pumps, heat exchangers and tanks
  • Measuring and control instrumentation
  • Process temperature stabilisation
  • Protection against weather conditions, especially during winter periods

SUM Heating Guard covers are also used as insulation jackets for transport containers (drums, IBC containers) in order to heat the contents prior to unloading or to prevent them from solidifying.

SUM Heating Guard covers are used as an active system which, in addition to their insulation function, is capable of protecting equipment against temperature dropping below a predefined value. Importantly, the cover can still be quickly removed from the equipment (together with all heating cabling), providing unrestricted access during maintenance or inspection work.
Inner and outer technical fabric layers – Glass fibre fabric coated depending on requirements with silicone or PTFE (also available in an antistatic version).Heating cable is integrated into the inner layer of the cover, while an external electronic thermostat with a power cable is installed on the outside – a ready-to-use plug-and-play system. On request, the installation can be supplied in an EX-rated version.Insulation core – Approximately 80% of our products utilise mechanically needled E-Glass insulation felt. Unlike conventional mineral wool insulation, it offers:
  • High density: from 130 to 180 kg/m³
  • Excellent water resistance – even after complete saturation, it regains 100% of its insulating properties once dried
  • Outstanding durability and mechanical integrity – resistant to deformation caused by bending, with no delamination or fibre breakdown
Other materials used include silica mats, synthetic rubber, Pyrogel and others.Fastening and edge finishing systems are always tailored to the specific application, taking into account operating temperatures, surrounding equipment and the user’s individual requirements. Available fastening solutions include industrial hook-and-loop fasteners (including high-temperature grades), stainless steel buckle straps (standard), drawstring fasteners, stainless steel hooks and other specialised fixing systems.Identification plate – Each cover is assigned a unique serial number, and its design specification is stored indefinitely in the SUM database. The identification plate may also include any information required by the customer, such as installation location, valve numbering or asset identification details.All fittings and fastening hardware used in every version of a SUM cover are manufactured from stainless steel.Exceptionally strong seams, sewn with stainless steel thread braided with Kevlar®, ensure long service life and excellent resistance to high temperatures.
