Application
While primarily designed for Ammonia, this Ammonia Refrigeration controls are also suitable for R-22 and other non-corrosive liquids that have a specific gravity of 0.5 or more. The controller is ideal for the control of the operating level of liquid in liquid refrigerant accumulators and separators. Although this is normally done with a solenoid valve, the controller canactivatean alarm or a pump or similar device.
Construction
Mechanical Float:
Mechanical Float: Lightdeepdrawn body, drawn inone piece. Ball &Stem are made from SS. This device consists of one float chamber with a magnetic operated switch in the top housing. The float chamber consists of a housing, float ball and magnet. The float ball is located inside the housing and moves an attached magnetic stem up or down in an enclosing tube from thetopand is protected by the enclosure. Gravity equalisation of the liquid level lin the float chamber is a function of the liquid. For fluids having a high viscosity the response time will beslower. The level controller should not be used on water applications.
Safe Working Pressure: 300 psi.

Controls, Coimbatore, India an ISO 9001:2015 TVE accredited company, leading manufacturing & Exports of Servo Voltage Stabilizer, Isolation Transformers, Frequency Converter, Two phase to three phase converter, Variable Transformer, Rectifiers, energy saving equipment in India. Our products are well appreciated world over and received much recognition for their quality.
Working Principle:
Beta multi-function static frequency converter is a standard AC power supply electronic device, it can simulate international standard power supplies, convert fixed AC voltage and frequency power into stable pure sine wave power by rectify internal AC to DC, DC to AC currying, with high activation current, and displays a number of parameters (Such as: voltage, frequency, current, apparent power, power factor etc.).
Beat static frequency converters adopt advanced PWM (Pulse Width Modulation) technology with compact size, light weight and high efficiency features. Digital Signal Processor technology provides high precision measurements function of voltage, frequency, current, apparent power and power factor etc. The use of high power IGBT module design to reduce circuit complexity, enhance frequency converter stability and reduce power consumption. And the isolation transformers completely isolate the mains and the loads, in order to improve the loads stability and a variety of testing performance, to ensure the accuracy of test values for the loads.
Beta frequency converter provides voltage 110v - 480v and frequency (standard 40Hz - 120Hz, 120Hz to 499.9Hz is optional), suitable for general commercial electrical and electronic machines.
Product Features:
Beta frequency converter is suitable for use with resistive, capacitive, inductive and non-linear loads.
50Hz, 60Hz or 400Hz input frequency.
Adjustable 110 to 480VAC output voltage.
