Heating cable or heating tape: how choose?

The heating cable or tape choice depends on a lot of elements. We are going to try to understand why. First of all, it’s important to define exactly and what you want to get taking into account the operating conditions. To help you in this process, the manufacturer has developed FLEXELEC appropriate questionnaires that you can download: questionnaire Flexelec product.pdf Don’t forget that little scheme will define the accessories needed to install FLEXELEC tape and heating cables. You will found a complete range of junction boxes, connection kit, thermostats, hygrothermostats, power modulator and fitting accessories. Then, simply contact us on our [...]

Refrigeration Cold door: different types of cables can be used

Cold room doors should prevent ice which avoids closing doors in factories. FLEXELEC uses heating cables which depend on the type of door. Indeed, if the doors are flexible or rigid anti-shock heating cables used will be different. Thanks to these doors heating cables are protected from ice. Here are 3 ways to protect doors from freezing cold. First of all, ”classic” cold room doors require a heating cable FLEXTRACE FTSO. This self-regulating cable is installed on the edge of the door which prevents the ice. In fact, the cable maintains and heats the temperature of the door. Then, “bumper” the cold [...]

Heat pumps, FLEXELEC, your best partner for drain heaters

Heat pumps are part of a growing market. In total, 4.5 million heat pumps have been sold since 2005 in Europe. FLEXELEC manufacture and supply heating cables to many large manufacturers.To prevent condensates from freezing FLEXELEC recommend to include a heating cable inside or underneath the condensate tray.                             The drain line heater range CSC2K has especially been designed and tested to be installed inside condensate trays. This product features: – a heating cable which integrated 1m cold lead, where the connection is fully water proof. – an [...]

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 [...]

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 [...]

Door heater for cold room doors

Flexelec has a number of options for protecting cold room doors or refrigerated cabinet doors with an effective and reliable door heater.  Flexelec provides the highest quality flexible heating products and components across a wide variety of industries and fields of work. Whatever the technical requirements of your project, and whatever the budget restrictions, Flexelec has built up a longstanding reputation of working closely with clients in order to find the right door heater, anti condensation heater or heating mat to meet their needs. If not heated, the cold room door accumulates water condensation around the door seal which then [...]

Frozen Condensate pipe – Solution for Condensing Boilers

With condensing boilers you might have (or possibly will) experience condensate freezing problems every winter if your drain is outside. Indeed, frozen condensate pipes prevent boiler operation and can result in a break down. To protect the boiler from freezing, our product acts to prevent the formation of ice inside the pipes. Each year thousands of homes are deprived in the UK because of freezing problems. The cause of the breakdown of your condensing boiler thus comes from the accumulation of ice inside the pipe condensate blocking drainage. This can result in the heat exchanger bursting in worst case scenarios. Depending on your set up it can result in a [...]

Heat Pumps: freeze protect the drains to avoid breakdown

Air source heat pumps have seen a very large expansion in the last 10 years in Europe as they are very energy efficient and therefore enable savings to be made. These pieces of equipment are designed following thermodynamic cycles and require periodic defrosting. These defrosting cycles are necessary for the heat pump to work efficiently; therefore defrosted condensate is collected into a tray underneath the heat pump and evacuated into drains. Unfortunately, when the temperature level is close to zero in winter, condensates freeze, ice accumulates in the drains and the tray which prevent the heat pump from working properly. This could also result in damaging the heat pump itself. To [...]

Frost protection dirty water networks

In the case of buildings located below the level of the sewer, using waste management process is necessary. It must ensure the continuity of evacuation of dirty water, even during the winter. The water column to expel remains house full, due to the non-return valve of the pump and if this part of the network is not buried deeply enough, the risk of frost is important, and could create a discharge and flooding.  By providing a highly localized heat in the harsh winter, the FLEXTRACE cables allows the evacuation of wasted water, even at temperatures as low as -20°C. The FLEXTRACE [...]
