Freezeprotection systems from 1/2 inch pipes – inside pipe

Thermal protection from the inside of a pipe is an innovative solution for preventing frozen pipes. Flexelec has manufactured and supplied a 230V version called FTX/10W/m for inside pipes above 1 inch in diameter since 1995. This product is safe to use in drinking water pipes as it is electrically protected via a metallic braid overlaid by thermoplastic insulation. However, for pipes below 1/2 inch in diameter the FTX cable is too big to be fitted correctly without blocking the water flow. This is why, in January 2012 Flexelec launched the first constant wattage cable to be used inside 1/2 inch pipes up to 35m [...]

Door heaters 24V VS 230V

The UK is one of the only remaining countries in Europe widely using low voltage systems for doors, threshold and frost heave These low voltage systems are composed of a transformer (230V=>24V or 48V) being the dearest part of the installation, whilst the heaters are usually very basic and single insulated.        VS                             Historically, before RCD 30mA protections became compulsory, the low voltage system was the safest solution and therefore widely developed. THIS IS NOW CLEARLY UN-NECESSARY as electrical protections mentioned above are now a standard and make [...]

Allowing car/train wash area to be clear of ice/snow during winter: FLEXFLOOR from FLEXELEC application

Allowing car wash areas to be clear of ice/snow during winter is an important issue. Automatic car or train washes can sometimes suffer closure because of impossibility to run in winter as a result of ice building up on the tarmac or the concrete of the bay area. FLEXELEC proposes solutions to this problem. By proposing our under floor heating cable range FLEXFLOOR, we offer the possibility of having the “washing bay” free of ice/snow and therefore allow its full accessibility in winter regardless of the freezing temperatures. FLEXELEC solutions include a heating cable embedded in concrete (or Tarmac) associated with a [...]

Heating cables and cold rooms: Which characteristics for what needs? Part 2

Following our interview with Pierre Gabriel, business director @ FLEXELEC. Pierre, how do we control a heating cable? A heating cable is considered purely resistive and can therefore be controlled by any of these following: capillary thermostats, hygrothermostats, electronic control… In some cases, this control is not necessary as heat is needed 24/7 (a cold room door frame for example) but it is nearly the only application where I would not necessarily recommend a control system. In any other situation, it is best to control the heater; this way the life time of the installation is drastically improved whilst large energy [...]

Heating cables and cold rooms : Which characteristics for what needs? Part 1

In view of many issues and discussions with professional's in the refrigeration sector we write an article grouping relevant information regarding the heating cable applications for cold rooms (floors and doors). In this first part, we talk about the implementation of heating cables and then, in a second article, we will explain the management and monitoring of the facility. Interview with Pierre Gabriel : business director of the company FLEXELEC. Pierre, what is the difference between heating cable and heating tape? There is no clear and precise term to define the difference between a cable, a cord, a tape, a [...]
