Hygienic Thermal Insulation – PZH Certification
SUM Higienic Guard covers are a product range designed for applications in the food, cosmetics and pharmaceutical industries, as well as in all areas where strict hygienic requirements must be met in direct contact environments. In addition to their standard high-performance thermal insulation and operational properties, these covers are also:
- easy to clean and maintain
- suitable for pressure washing
- resistant to water, oils and acids
- equipped with light-coloured hook-and-loop fasteners to facilitate visual assessment of contamination levels
- non-dusting and approved for installation in direct proximity to food products
SUM Higienic Guard covers hold a Hygienic Certificate issued by the National Institute of Public Health – National Institute of Hygiene.
SUM Higienic Guard covers as thermal insulation jackets for industrial valves and equipment, designed for cleanroom applications in the food, cosmetics and pharmaceutical industries, are suitable for equipment operating in both high and low temperature conditions:
- Water, steam and thermal oil systems
- Valves, filters and flanged connections
- Pumps, heat exchangers and tanks
- Measuring and control instrumentation
Thanks to the use of specialised insulation materials and well-engineered design, SUM Higienic Guard covers are widely used on installations located in direct proximity to products manufactured under hygienic conditions. Metal-detectable threads have been used, and all dust-generating elements have been eliminated from the construction.
A separate application area includes cold process installations such as ammonia, glycol and chilled water systems. The cold-protection variant of SUM Higienic Guard covers eliminates issues such as condensation and ice build-up, which are commonly observed on uninsulated components of such systems. The covers significantly reduce service intervention time (no ice formation on valves and fittings) and improve the energy efficiency of distribution lines.
The covers are designed for repeated use and are not damaged during removal.
Inner and outer technical fabric layers – Glass fibre fabric coated on one side with PTFE (Teflon).
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
Synthetic rubber mats, Pyrogel and other materials are also used.
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), stainless steel hooks and other 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 in every version of a SUM cover are made of stainless steel.
Exceptionally strong seams, sewn with stainless steel thread braided with Kevlar®, ensure long service life and high thermal resistance.
