Heat capacity – The relationship between the heat supplied to a body and the temperature rise resulting thereof is called the heat capacity C of the body:
C = d Q / d T
The unit of the heat capacity is J/K.
The specific heat capacity c [J/m*K; J/m²*K; J/kg*K; …], often abbreviated to specific heat or also inaccurately referred to as heat capacity, is a thermodynamic chemical property. It measures the capacity of a material to store thermal energy.
To design a heat exchanger, the specific heat capacities both of the medium to be tempered and the tempering medium is of decisive importance as this allows, amongst others, to calculate the corresponding volume flows.
Heat exchanger – The transfer of thermal energy from one material flow to another takes place in a suitable appliance, the heat exchanger.
STRIKO heat exchangers are specially designed to temper viscous to highly viscous media – reliably and smoothly up to a viscosity range of 500,000 mPas. This is made possible thanks to the S-Helical technology patented by STRIKO, by means of which the medium to be tempered is kept in constant motion and rearranged from the centre of the tube to the tube wall and back, a procedure which prevents fouling and improves efficiency.
Holder (inlet and outlet part) – The use of bursting discs in bursting disc holders ensures the reliable functioning of the bursting discs. In the holder, the metallic sealing gasket between the bursting disc and the holder inlet part is established – either by using the screws of the flange connection (standard holder) or by the four high-strength screws integrated into the pre-loaded holder. The holders are usually designed in common high-grade steels like 1.4571 or in special materials like Hastelloy®. For graphite bursting discs, holders made of graphite, special materials or even stainless steel with PTFE-coating are used.
