LICO – Custom-made heat and overheat detector units for industrial and hazardous areas

The use of fire detectors is a conventional method. But when there is smoke or fire, it can be already too late. Why not detect heat and overheat before it turns to fire?

In case of smoke or fire, the security system (if there is one) alarms the personnel, the fire extinguishing system operates, the local firefighting department is notified, etc. These actions are designed to handle the abnormal situation, when the fire is already there. We can save more human lives, time and dramatically reduce cost if we concentrate more on early heat and overheat detection to prevent a fire or explosion.

LICO provides the right solution with a wide range of custom-made, certified heat-detector units and systems concentrating on the fire prevention.

The higher the normal operating temperature, the more passive fire-detection products come into focus.

HDL products are almost always custom made to suit the requirements of the customer and/or local system integrator. We cover a wide range of industrial use, such as engine rooms, transformer stations, wind generators, saunas and kitchens, and also hazardous applications, such as painting rooms, gas turbines, offshore platforms, oil refineries, nuclear power plants and many more.

ATEX, EN 54-5, CE and ISO 9001 certificates ensure the highest level of technical specification.

Our HDL heat and overheat detectors are based on bimetallic heat-detector switches, free of electronics, to provide the best reliability in high-temperature applications and also during harsh environmental conditions. Simplicity runs through the product family to provide easy installation and very cost-effective maintenance. Various alarm temperature settings are available from 140°F (60°C) up to 950°F (510°C) in N/O or N/C potential free contacts, which ensures fast integration with practically all existing and new systems.

The sensors in the HDL units are designed with rate compensation. This function provides a unique advantage over both fixed temperature and rate-of-rise types of detectors. They accurately sense the surrounding air temperature regardless of the fire growth rate. Fixed temperature detectors must be completely heated to alarm temperature and therefore a lag in response time may occur with a fast rate of fire.

Rate-of-rise devices, on the other hand, are triggered by the rate of increase in ambient temperature and are subject to false alarms caused by harmless, transient thermal gradients, such as the rush of warm air from process ovens.
