Welcome to Peccater

Often affecting low value equipment but causing damage way beyond their intrinsic value elevated temperatures are an insidious killer of property, products and people – faulty connections are a key ignition source in the fire triangle.

In electrical installations the latest available UK government statistics show 8594 accidental dwelling fires due to 'electrical distribution' and 'other electrical appliances', resulting in 28 fatalities and 1214 non-fatal casualties; in 'other buildings' faulty appliances and leads account for 34% of all accidental fires, in this sector fires are estimated to have cost £2.5 billion; these are only the official statistics it probable that the costs of overheating are much higher, similar statistics can be found for all the world’s leading economies.

It is probable many incidents arise from loose or faulty connections; standard protective equipment often does not detect the effects of overheating sometimes being the location of the faulty connection themselves. Smoke, heat alarms and sprinkler systems only react when an incident is established; extinguishing a fire once established will entail further cost from water damage.

The solution is to detect the elevated temperature before the damage is done. Thermiac devices from Peccater Safety Products offer a unique solution to the problems caused by overheating, operating when the local temperature exceeds 80oC thus preventing damage to components, cables, connections, bearings, motor or transformer windings, electrical ballasts, PCB boards, electrical wiring accessories in fact in any situation where elevated temperatures can cause degradation or pose the risk of fire.

In normal conditions (below 80oC) the Thermiac device is in an open condition with the contacts held apart by a specially formulated compound, in fault conditions (above 80oC) the compound releases the spring loaded contact closing the circuit thereby operating an alarm or trip as required. This operation is non reversible so a positive indication is maintained showing that the installation has been subjected to a thermal event, this is particularly useful where the heating was due to a transient effect and is a very effective way of detecting elevated temperatures have occurred. A good example is vehicle axles or bearings where temperatures in excess of 80oC may be the precursor of a future failure.

The Thermiac devices are manufactured for Peccater Safety Products by a world leading component manufacturer Vishay Corporation and are fully protected by worldwide patents.
