Loval living
Loval convector elements

Loval designs and produces a wide range of air- and liquid cooled brake load resistors optimized according to customer specifications.

The core of Loval heating elements is well protected against demanding ambient and temperature conditions.

Loval convector elements

Heat transfer of air cooled load resistors is based on either natural or forced convection. In natural convection the heat is conveyed by the rising air from the heating elements.

Dimensioning is based on required power and load curve Materials can be chosen from unalloyed and alloyed steels. Fan assisted cooling can be used in air cooled solutions whilst in high power application..

Applications include e.g. load resistors of frequency converter drives of e.g. cranes, oil rigs, rolling stock equipment and various industrial applications.

Advantages

  • Feasible for various operating conditions
  • Long service interval
  • durable in high temperature environment
  • approved and certificated solutions
  • Tubular element protects resistor core

Loval convector elements

Loval finned elements are designed for air heating in high power and limited space applications, e.g. fan heaters, room heaters, duct heaters and load resistor banks.

Dimensioning is based on required power and air flow rate. Materials can be chosen from unalloyed and alloyed steels.

Finned elements are used when required power is relatively high but there is a limited space available for installation. Also fans can be added for forced air flow. It is possible to add thermostats, over-temperature cut-outs and connecting cables to the elements.

Typical applications are rolling stock, generators and motors

Advantages

  • Brazed fins guarantee excellent heat transfer
  • Proven and safe construction

Durability in vibrating environment i.e. rolling stock

If necessary, also thermostats, over-temperature cut-outs and
connecting cables can be added to the elements.
