We offer a range of Protectors and Monitors such as AC relays are available for Over load (OL), Single Phasing (SP), Phase Reversal (PR), etc. We offer Overload relays in 1ph and 3ph types. 1ph-relays are useful for single phase load and are used as cost-effective solution for 3 ph applications whenever load is balanced. The classification of this category is as follows:

• Instantaneous (INS) type:- This relay changes the state as soon as overload occurs.
• Time-Delayed (DLY) type:- The relay changes the state soon after elapse of present period from the time overload occurred & stayed.
• Jam (JAM) type:- This control relay does not respond to the overload condition for a preset time, from switching on the load but as it elapses, the relay responds instantly to overload.

We offer a wide range of burners used for specific applications such as Flame Treatment gas burner for Plastic Printing, custom shaped gas burner for thermal sealing, automated gas pilot burner, etc. Our range of burners includes:

• Gas fired Ceramic/ Steel braiding burner
• Medium wave Infra Red burner
• Mono-block gas burner
• Forced draft pipe Gas burner
• Auto-ignited and monitored Pilot burner
• Air aspirated burners such as V-burner
• Ribbon burner
• Fish Tail burner and Gas Curtain Burner.

Detection of burning flame is achieved with the use of sensors to make sure of the following characteristics of flame:

Visible bright yellow/white light

Infra Red radiations

Ultra-Violet radiations

Ionic Current

It is a universal truth that a burning flame gives out infra red and ultra violet radiations of diverse frequency. The sensors sense the flame and the sensors are usually delicate, costly and required to be operated below 50 deg C. Line of sight of flame and feasible direction of installing the sensor gave rise to two types of sensor enclosures; Front Viewing (FV) and Side Viewing (SV) types.

We have evolved new techniques to detect and monitor flames. Our range of Diligent Flame monitors sense the intensity, type and size of the flame. Our range of flame monitors includes;

• Flameye PR for Oil Flame
• Flameye PV for Oil Flame
• Flameye IR (Infra Red) for Coal, Oil & Gas flames
• Flameye UV (Ultra Violet) for Oil & Gas flame
• Flameye N (Ionisation) for gas flame
• Dual Flameye UI (UV & IR) or UU (UV & UV)
• Flameye with Flame-ON or -OFF Delay
• Flameye as Import Substitute for most of the popular types.

Diligent flame sensors & enclosures like photo voltaic type PV-EYE-SV Diligent Photo Voltaic flame sensor develops dc voltage proportional to the intensity of visible light incident on the sensor. It is available in only side viewing type. This flame sensor serves the same purpose like photo resistor sensor but is costlier.

We offer a wide range of diligent burner controllers whose classifications is based on the type of fuel burnt, design of burner, mode of operation, technique of flame sensing, starting pre-requisite interlocks, security interlocks, etc. Our burner controllers are manufactured in either base mounting type or door mounting type.
