Elesa insulated handle used for industrial heater

1 min read

An engineering solution was required for a new project that needed a handle that complements a machine operating up to a temperature of 250°C.

Keller specialises in the production of machines for industrial printing across a variety of sectors. The machine heats moulds and maintains low cooldowns, with changeover times being a crucial factor for optimal operations.

Elesa proposed the MMT. handle for heat insulation, which has been adopted by Keller.

The MMT. handle is composed of a round steel cross section bar, with fine ground matte chrome-plated surface and a heat insulation element in glass-fibre reinforced polyamide-based technopolymer that is available in black, with matte finish.

A series of internal aeration canals of the technopolymer heat insulation element provides heat insulation, which minimises the heat transfer to the operator’s hands to ensure a firm and safe grip. The ergonomic design helps to facilitate the grip, keeping the operator’s fingers away from the heat source. The handle is also suitable for use on opening doors of stoves and fireplaces.

Testing was carried out internally via Elesa laboratories with continuous working temperatures up to 200°C. The results showed that the MMT. handle transmitted a temperature between 65°C and 90°C on the element in technopolymer.
