Product catalog summary

Overview
This document outlines the specifications and guidelines for various tank heaters, including VR immersion heaters, screwed-in heaters, cartridge heaters, tube heaters, and oil pre-heaters. It includes product descriptions, assembly instructions, order codes, and performance data.

VR Immersion Heaters

Designed for direct pre-heating with a stable welded version.
Features easy installation, no lateral tank machining, and low minimum oil level in horizontal position.
Includes magnetic clamps for iron particle pickup and protection class IP 68.
Integrated thermostat with a switch-off temperature of +40°C and a temperature limiter for direct switching.
Constructed from stainless steel, brass, and plastics, resistant to fluids like HLP and HFA.

Screwed-in Heaters

Used for pre-heating hydraulic oil on a mineral oil base, suitable for horizontal mounting under oil level.
Surface charge approximately 1.5 W/cm² for hydraulic oils, with a bright galvanized steel cap.
Includes series PTHK 90, PTHK 92, and RHK with various protection classes and temperature control options.

Oil Pre-heaters (EDH Series)

Designed for pre-heating hydraulic oil, heating oil, or other hard-inflammatory agents.
Features a heating element bundle with baffles to avoid carbonization temperature.
Mounting can be vertical or horizontal, with heating capacity ranging from 0 to 90 kW.
Recommendations include installing a flow control and ensuring baffles are cooled down post-operation.

Performance Data

Performance data for various EDH models are provided, based on a medium intake temperature of 5°C.
Details heating times for different tank sizes and desired temperature increases, showing model efficiency.

Technical Specifications

Maximum operating pressure is 16 bar, with higher pressures available on request.
Operating temperature ranges from 0 to 95°C, with other voltages available upon request.

Tank heaters Product description • For the pre-heating of hydraulic oil, heating oil or other hard-inflammatory agents • The fluid to be heated is lead through a heating element bundle with the aid of baffles • With pre-determined minimum flow rate a sufficient flow velocity is reached • Thus, the carbonisation temperature is avoided • The mounting position is either vertically or horizontally. Vertically: Provide electrical connection on top. • Temperature limiter at 100°C (wihtout EDH-500) • Installation of a flow control • Avoid after-heating effect / Make sure that baffles are cooled down...
