Description

Main specifications

Assembly ends

Glass-fibre reinforced polyamide based (PA) technopolymer, black colour.

Support

Aluminium in natural colour.

Level column window

Transparent tube in PYREX®* glass, also suitable for use with glycol-based solutions.
Maximum fluid level visibility even from side positions

Transparent front protection 

Polycarbonate (PC), extractable for cleaning operations

Screws, nuts and washers

  • HCK-GL: : zinc-plated steel screws with hexagon socket, nuts and washers.
  • HCK-GL-SST: : AISI 303 stainless steel screws with hexagon socket, AISI 304 stainless steel nuts and washers.

In any case we suggest to verify the suitability of the product under the actual working conditions.
Fitted to the aluminium support.

Maximum continuous working temperature

  • HCK-GL: 100°C (with oil, water, glycol-based solutions).
  • HCK-GL-SST: 130°C (with oil, water, glycol-based solutions). In laboratory tests these indicators showed an excellent resistance to temperatures up to 150/160°C for many hours with pressures of 5/6 bar.

General information

TECHNICAL DATA

In laboratory tests carried out with mineral oil type CB68 (according to ISO 3498) at 23°C for a limited period of time, the values of pressure resistance were much higher than 35 bar.
If you need to use the indicator with other oils or fluids and under different pressure and temperature conditions, please contact ELESA+GANTER Technical Department.
In any case we suggest to verify the suitability of the product under the actual working conditions.
