Product Overview

Since our commencement year, we Cressall Resistors are manufacturing, exporting and supplying a supreme quality range of Dynamic Braking Resistors. These resistors are manufactured at our advanced manufacturing unit under the stern observation of our experts. Our offered resistors are manufactured using optimal quality raw materials with the help of ultra-modern technology in line with global industry standards. Provided resistors are mainly used to control the braking and dissipating of the excess energy. Additionally, we provide these Dynamic Braking Resistors in several specifications at affordable rates to the clients.Features: Compact design Suitable for any power rating Perfect for any make of drive Easy to install Stopping of electric motor driven machinery creates an energy through motor itself, which acts as a generator. This breaking of energy requires to be put back into power supply dissolute like heat. To get a compact and cost effective method of controlling breaking and dissipating, the excess energy required to be produce. Following are the most common types of braking resistors: Braking Resistors for Industrial Markets Braking Resistors for Marine Markets Cressall manufactures Dynamic Braking Resistors DBRs are manufacture in the way that it can be adjust its resources according to the requirement with power rating from few watts up to many megawatts and with any duty cycle for various applications. Applicable for various power rating and duty cycle Applicable for any make of drive Available in many designs such as standard or custom size designed Compact and economical Enclosed, open banks or loose coils Continuous powers up to 25kW, braking power up to 250kW ES and DBR range of high capacity DBRs which is  used for regenerative braking are offerde by Cressall at a low cost which can be itemize easily to specific, installed easily and suitable for most commonly used inverter drives.   The product can be suppl either from storage (in the UK from our distributor CP Automation) or can be manufactured within few days. Continuous powers to 100kW, braking power up to 1MW Cressall SD and HPR DBRs are extremely applicable for continuous powers to 100KW. To built to a standard design is the reason behind the manufacturing of these SD and HPR DBRs and can also be supplied in  few weeks IP20 or 23 can be enclosure degree of protection; 304 or 316-grade stainless steel are the properties of this, but it can also be painted or Enclosure degree of protection can be; materials are usually 304 or 316-grade stainless steel, but if it is necessary then it can be painted or stimulate mild steel.General Applications: Applicable for continuous energy of more than 100 KW for the use as medium and high voltage with fan or water cooling and can also be suitable for various applications such as mining, marine, etc. We can design a custom resistor as per the client's requirements older designs include: 316 stainless steel,800kW continuously rated fan cooled, deck-mounted for pipe laying vessels. Fresh water-cooled for winch braking is 1.0MW continuously rated. For use on the third rail of a metro system, 1.5MW continuously rated naturally cooled, silent operation. For hazardous environments 15MJ air to water cooled IP56 closed loop is the unit. Applications of Braking Resistors in Industrial Markets: There are various applications for braking resistors in industrial markets. Some of them are as follows: Cranes: When a crane is being utilized to bring down an overwhelming burden, it needs to battle with surplus potential energy, which could bring about the engine to flee in an uncontrolled way, resulting making a security risk. A braking resistor can be utilized to avert this from happening. Lifts & lifts: When elevators are plunging and conveying individuals there is abundance potential energy, which has a tendency to drive the lift engine in opposite, therefore making it work like an alternator. A braking resistor can be utilized to disperse the undesirable electrical energy. There are some reason fabricated units for this obligation, designed for roomless lifts and for fitting inside the structure of an elevator. These resistors have exceptional EMC association encloses which are obliged open structures and can give assurance against clammy and dust. Electric Trains: Dynamic braking resistors are regularly utilized as a part of conjunction with air powered brakes in electrical trains to diminish the measure of wear on mechanical segments. When it is exchanged into circuit the braking resistor causes the current to stream the other way to when the train is motoring. In this manner, the engine applies a torque that restricts the forward movement. Wind Turbines: Braking of a wind turbine can be accomplished by "dumping" energy from the generator into a braking resistor. This strategy is helpful if the motor load on the generator is all of a sudden lessened or is too little to keep the turbine speed inside of its permitted point of confinement. Likewise, in speedier winds, it is conceivable to present patterned braking, which causes the turbine sharpened pieces of steels to back off. This builds the slowing down impact, hence lessening the productivity of the cutting edges. Thusly the turbine's rotation can be kept at a protected velocity. Applications of Braking Resistors in Marine Markets: Dynamic braking resistors applications in Marine industry are as follows: An essential advantage from utilizing an electric drive is that dependable frameworks of regenerative and element braking resistors are accessible to supplement or supplant customary mechanical slowing mechanisms. The upsides of electric braking incorporate control, unwavering quality, mechanical straightforwardness, weight sparing, and there are opportunities where there is a chance to utilize regenerating braking energy. Braking resistor technology has evolved much in marine applications, especially in resistor designs and functionality. There are some braking technologies where the main propulsion brakes energy go beyond many Megawatt. The cooling methods, which comprising of liquid, forced air and natural convection. The designs of braking resistors are devised in a way to make it less susceptible to physical impairment, thwart accidental contact with life possible voltage, thus suitable in operating in marine environment.
