Ventilation Systems

Air Conditioning systems provide and maintain internal air conditions at a pre-determined level, regardless of the time of year, the season, and the external atmospheric conditions. It is important to provide sufficient fresh air for the room occupants with any type of air conditioning system. Under part L of the building Regulations minimum requirements have to be provided by legislation.

Central Plant/Ducted systems combined with heating, humidification or dehumidification, filtration, and heat recovery can achieve almost any pre-set internal conditions, ensuring the optimum total environment required for your application or process. This type of system also allows complete control over the conditioned air, and the option to utilise several different control strategies.

VRV/VRF systems can provide cooling and heating for large offices and less complex areas, with multiple ceiling mounted cassette or ceiling concealed fan units for each single external condensing unit. But still need a fresh air system to provide the minimum tempered fresh air for the occupancy of the area.

Heat recovery enables a system to recover up to approximately 50% of the energy from the extract airstream of a ventilation system. As environmental issues become increasingly influential in the design of mechanical ventilation systems, the inclusion of a heat recovery facility can contribute to considerable energy savings, and the reduction of related carbon emissions.

The most common type of heat recovery used for ventilation systems, is the plate heat exchanger. Energy is transferred from one air stream to another with no cross contamination. In areas where the input and extract systems are remote from each other, a run-around coil system can be used to overcome practical installation issues.

A more efficient heat recovery system used on large commercial buildings or where is odours .fumes or Volatile organic compounds hazard us to health is the rotary zeolite wheel. This allows the heat to transfer though a revolving honey comb heat exchanger and a 100% of the exhaust air goes to atmosphere.

Heat pumps are now available to save even more energy when heating and cooling and the running cost of these can be dramatically reduced when combined with ground source or water source heat exchangers. As with a refrigerant system you are using the temperature difference in the ground to harness the energy for both heating and cooling .There grants and capital allowances available for this type of energy efficient system.

ecs has designed and installed several Fully ducted Air-conditioning systems in Office Blocks, Hotels and Food and Pharmaceutical production areas Automobile production areas some complete with VRV and VRF systems and one major System with a lake ground source Water cooled condensers for heat recovery.

ecs has provided Replacement air systems for Paint shops, boat building, ware houses aircraft hangers welding shops, Food manufacturing, Pharmaceutical production .Where all the above forms of heat recovery systems have been installed.

Most of the systems provided have been complete turnkey projects
Ventilation systems can help reduce the oppressive atmosphere created by hot, stuffy working conditions. The introduction of fresh air and the subsequent removal of energy and airborne contaminants created by equipment/machinery and manufacturing processes can greatly contribute towards a more productive workforce and is an essential part of providing a comfortable working environment.

It is important that an extract ventilation system is balanced by an input or make-up air system to maintain the displaced extract air.

Target Ventilation systems provide a cooling 'effect' by directing tempered fresh air to areas that operatives occupy frequently, providing temporary respite from the uncomfortable surrounding areas.

Dirivent Systemecs have a range of Air distribution systems such as conventional HVAC ductwork and grilles, to textile duct distribution passive displacement systems and directional ventilation system such as DIRIVENTTM for large industrial buildings, which we are proud to be the UK licensee.

The DIRIVENTTM system provides full control over temperature and air flow in all types of buildings from low bay air conditioning to high bay heating and cooling. The key element is in achieving the correct working environment, is to create evenness of the air temperature throughout the occupied space, DIRIVENTTM can provide this as all the air is continually entrained and mixed by nozzle air jets.

ecs as the licensed designers and installers have installed this system in Training Academy, Showroom, Ware Houses Car production facility There are over 5000 DIRIVENTTM Installations World wide Making it one of the most popular systems due to it cost effective design and outstanding running costs.

Textile Ventilation SystemsWhere the air needs to be delivered in large volumes in a concentrated area we can offer Textile duct passive displacement systems these have the benefit of reduced drafts, easy to take down and wash clean this system can be used for both heating and cooling using the same plant and equipment as a conventional air conditioning system.

ecs has provided complete turnkey installations in the Food and Automobile industries but it can be used in leisure buildings, Pharmaceutical buildings. Converted factories into open plan offices as an cost effective ventilation solution.

ecs provide ventilation systems for clean rooms, and filtration systems for dust, odours fumes and oil mist and gases.

The health and safety of the workforce is one of the primary reasons to ensure your ventilation systems comply with current regulations. EPA, Cosh, Health and Safety Codes Of Practice Guidelines for all industries.

Increasing Health and Safety legislation requires that exposure limits are adhered to and the installation of local exhaust ventilation (LEV) system can help in reducing airborne contaminants and toxins.

The provision of filtration elements within the plant also ensures that fumes/odours generated from your processes do not become a nuisance to adjacent properties, an increasingly common requirement of local authorities.

Where manufacturing and other processes generate airborne particulate, a dust extraction system, including capture hoods and LEV enclosures, can greatly improve the internal environmental conditions.

ecs has designed and installed Extract systems for Dust from tissue paper machines, pepper mills, snuff, cast iron, sugar, and Paint particulate Grinding and fettling booths.

ecs has designed and installed Odour control systems for Cat Food, Toilets, Scents from bottling plants, hydrogen from process lines, Fume dilution from Natural Gas Burners.

ecs has designed and installed systems For hazardous fumes from styrene, Paint coagulation, Foam laminating smoke, Oil Mist, Benzene, Engine Exhaust Fumes, Welding fumes, Plastic laminating machines, Battery charge areas, chlorine fumes from swimming pools. Generator fumes from a Ships Engine room.

ecs has designed and installed Filtration systems for all classes Clean rooms, Photo sensitive plate production areas Food production areas.

ecs carry out Replacement Plant and Repairs to ventilation existing systems we have recently carried out the replacement of 6 plant rooms including the air handling units on board ship in dry dock in Malta. We have repaired and changed duties to extend the life of existing air handling units. We are used to working in occupied areas and caring out extensive refurbishment projects.
