A revolutionary resistor designed for low and medium voltage applications, especially severe conditions in automotive, traction or marine systems.
Manufactured from advanced materials the EVT and EV2 have a patented design that encapsulates and totally separates the resistor elements from the water based coolant providing a modular, light weight, low volume, high power solution for water cooled applications.
Typically the EV range are 10% of the volume and 15% of the weight of the equivalent conventional convection cooled DBR. Units can be combined together to handle from 10’s to 100’s of kW and supplied as individual components, frame mounted assemblies for integration in customer’s systems or completely enclosed multi-banked systems that include inlet/outlet manifolds, flow and temperature monitoring.
The latest hybrid/electric vehicle developments mean there is an urgent need for a new approach to regenerative braking. Our EVT resistor with its lower 10kW power rating and reduced pressure drop provides the higher reliability, mechanical simplicity and low weight demanded.
The EVT is the most cost effective way to ensure any excess energy the vehicle produces is safely and efficiently recycled within the car itself. The need for three independent braking systems in hybrid/electric vehicles means that regenerative braking using the EVT is the greenest way for these vehicles to dissipate energy.
Our EV resistor range provides dynamic braking of all types of low and medium voltage AC drives in:
- Hybrid and all-electric vehicles
- Winches and cranes
- Cable laying vessels
- Propulsion drives on ships or oil rigs
- Dummy loads and discharge resistors for MV electrical systems
- Liquid heating
- Patented design that encapsulates and totally separates the resistor elements from the coolant.
