JD Turbulators B.V applications

Turbulators for Gas Boilers

For more than 40 years our turbulators are used in fire-tube boilers to increase its efficiency. Often strict pressure drop limitations exist due to the maximum ventilator capacity. Our left-right twisted turbulator design is known to have an optimal ratio between pressure drop and heat transfer with a gaseous heat medium. Based on our own pressure drop and heat transfer correlations JD-Turbulators can make a calculation of the optimal turbulator geometry and material with the given dimensions and conditions of the boiler. Whether it concerns mass-produced floor standing hot water boilers, one-off (special) boilers, steam boilers, spare parts and replacement, or boosting the efficiency of existing boilers. Our turbulators have increased the efficiency and system size and cost of tens of thousands of boilers worldwide. Generaly an efficiency increase between 2 and 5% is to be expected with a much lower investmentcost in comparison with e.g. an economizer.

Turbulators for Biomass Boilers

Next to increasing the heat exchanger efficiency, turbulators are used to clean scale deposits of the fluepipes from biomass boilers. As fouling in the heat exchanger is the primary cause of a decreased boiler thermal efficiency within time. Cleaning of the heat exchanger tubes of biomass boilers is essential to restore maximal system performance. Our spiral turbulators are an economic solution for both cleaning and efficiency for many biomass boiler manufacturers in Europe.

Turbulators for Air Heaters

The value of applying turbulators in air heaters and radiant tube heaters is known for decades. With more stringent efficiency norms such as the new Eco-design, its use is becoming more and more popular. With turbulators the desired efficiency can be obtained with a considerable smaller heater design.

Turbulators for Heat Exchangers

Our spiral turbulators can be an interesting option for heat exchangers, coolers and condensers when the flow regimes and viscosities of the cooling fluids are such that it is causing a laminar flow. We are able to manufacture our spiral turbulators in twist ratios (360^o pitch / width) between 2,6 and 12 and in a wide range of dimensions and materials, ensuring application in a broad range of heat exchanger devices. For instance a recent application of our turbulators within heat recovery shower drains. Our spiral turbulator applied in heat recovery shower drains increased its efficiency such that the shower drain meets the latest Dutch EPC-norm, the energy performance standard for the build environment in the Netherlands.
