Fast delivery: For same day dispatch of stock items (ES and DBR) in the UK contact our distributor: CP Automation before 10.00am. Units not held in stock can be manufactured quickly.
Performance: Our range of elements combine excellent heat dissipation for continuous braking with the highest active surface area per kW in the industry, giving outstanding short-time performance for repetitive braking duties.
Confidence: Our experience in supplying resistors for electric motor brakes combined with accurate sizing software means we can predict the performance of your resistor for any specified duty cycle.
Cressall ES and DBR braking resistors are based on two types of resistor elements:
HP Coils: spiral wire-wound coils on ceramic formers
ZC Coils: edge-wound coiled strip on ceramic formers
Both elements offer high overload capacity and rapid cooling.
The alloys used have low changes in resistance over the temperature range: no more than 18%, unlike designs using 304 stainless steel which can increase in resistance during the heating cycle by as much as 50%, resulting in lower braking currents and less effective braking.
ES Series, 0.6 – 8kW Continuous
DBR Series, 9 – 25 kW Continuous:
For higher power applications Cressall offer expanded mesh and HPR grid resistor designs, well proven in regenerative braking applications around the world.
With these elements we can offer flexible and cost effective solutions for higher powers and heavy overloads.
Units are designed to meet the customer’s specified duty but are based on standard formats, meaning that design, manufacture and despatch can be in just a few weeks.
