Ethylene propylene rubber
Ethylene propylene rubber is one of the different types of rubber used as a packing material in shaft seals to prevent the pumped media from leaking.
Europump
The European pump manufacturers are represented in the organisation Europump which provides expertise on technical issues and can also be used for exchanging pump related information.
Evaporation
Evaporation takes place in an evaporator, which is a part of a cooling system. The change of state from liquid to gas of the cooling media flowing through the evaporator is known as evaporation.
Evaporative condenser
An evaporative condenser is used to remove excess heat from a cooling system when the heat cannot be utilised for other purposes. The excess heat is removed by evaporating water.
Evaporator
An evaporator is used in a cooling system. An evaporator absorbs heat from the surroundings, for example by cooling the surrounding air.
Exfiltration
Exfiltration refers to the leakage of wastewater into soil and groundwater through faulty joints, damaged pipes, around manholes, etc.
Expansion of fluid
When a liquid is heated it expands, i.e. its density falls as temperature increases. The temperature of a liquid in a heating system will vary significantly over time.
Expansion
Expansion is an expression used in a cooling plant. It relates to the temperature and the process that brings the refrigerant from the condenser side to the evaporator side in the cooling plant.
Fan coil
A fan coil is used to heat or cool down air in many different types of locations, for example; in production areas in the food industry, warehouses, offices, supermarkets, etc.Since it does not have any ductwork, a fan coil unit is used to control the temperature only in the space where it is installed.
Fan
A fan is a device with wings or an impeller that rotates by means of an electric motor. Upon the rotation of the wings or impeller, air is set in motion. The rotation causes the mechanical work to be transferred to the air.
