Air handling unit (AHU) repair and refurbishment VES Specialist Site Services can refurbish any model of existing air handling or packaged air conditioning equipment, including those supplied by other manufacturers. The refurbishment of existing air handling and packaged air conditioning equipment is a practical   alternative to replacing with new. Those with experience of on-site refurbishment quickly realise the benefits:Cost effectiveness Typically, the refurbishment cost of existing equipment is 35-50% of the cost of new, this excludes the removal and re-installation costs. New components can often be flat packed to further save crane and road closure costs. If budgets are tight, quotes can be provided to give an itemised list, so works can be limited to essential items only.Less disruption, more flexibility Works can be scheduled so as not to interfere with a client's business or their neighbours. VES can even carry out works overnight or at weekends.

Refurbishment is often a quicker option from start to finish than replacement. It also gives the choice of separating the necessary works and completing at different times for greater flexibility. For instance, a gas burner can be replaced one weekend, casework and other components on another. A controls upgrade that can integrate with BMS could follow, with other equipment on site. This could include adding a cooling coil, heat recovery, higher grade filtration or upgrading fan performance. Increased efficiency means running costs can be improved by a considerable margin. What can be refurbished? A lot can be achieved with equipment in poor condition. The example below shows the in-depth AHU refurbishment process that VES offers. If properly maintained, Specialist Site Services can give another 15 years working life to existing equipment. Roof panels are often the main cause of deterioration of an expensive AHU. Depending on budget, they can be treated or replaced.

Specialist Site Services can replace damaged top panels and add an external covering. For large roofs, particularly those with irregular shapes, Specialist Site Services offer a polybutyl seamless roof, with a 10 year guarantee. This is particularly useful on units with high suction pressures that tend to pull water through roof sections, causing rusting.portable ac units work Heating and cooling coilscentral ac units for sale mn For units with restricted access, replacement coils can be provided in sections which are then joined on site, replacing valves and actuators as required. window ac unit vent open closedCoils can also be flat packed to suit further restricted access situations. Specialist Site Services can repair or replace any make or model of gas heater in AHUs.

DampersJammed dampers are one of the biggest causes of incorrect AHU operation and can easily be repaired or replaced. FiltersMany older units have poorly fitting filters allowing bypass of unfiltered air. Specialist Site Services can replace filter frames to prevent this and often fit higher grade filters as required. All fan types can be repaired or replaced. Also, fans can often be replaced with the latest energy efficient direct drive fans, as below, and inverter controlled. Replacing old forward curved fans with new plug fans can use 15-20% less energy. Regular maintenance is the most effective way of making energy savings and extending the life of air handling equipment. A maintenance agreement with VES will keep your AHUs in peak condition all year round - contact us for more details.

Energy-saving & environmental features Aluminum-Silicon heat exchanger delivers high efficiency - 95% with low temperature applications Low NOx emissions ahead of 2012 SCAQMD regulations Simple, intelligent control options optimize efficiency and fuel consumption Low electrical consumption when the boiler is in standby mode Electronic ignition Anti-cycle and modulation control End user comfort & convenience features Limited lifetime heat exchanger and 5-year parts & labor warranty All models available as NG or LP Special insulation ensures ultra-quiet operation Compact dimensions and built-in frost protection offer flexibility for location of installation ECO mode for energy saving fuel consumption Exclusive safety feature - keypad safety lock prevents unwanted tampering with heating controls Eligible for Tax Credit where available

Each unit features an ASME approved Al-Si heat exchanger constructed of advanced Magnesium-Aluminum-Silicon alloy - offering increased flexibility versus traditional stainless steel. They are equipped with highly durable heating blocks that are corrosion resistant and designed to optimize clean burning combustion over an extra large surface area, which requires minimal servicing and reliance on spare parts during the boiler’s lifetime. Plated stainless steel heat exchanger All Greenstar Combi boilers are equipped with a high-strength stainless steel secondary exchanger and burner with double passage - ensuring consistent temperature output based on demand. The DHW hot water temperature control limit of 140°F helps prevent scale build-up within the heat exchanger. Full modulating fan assembly A full modulating fan automatically increases or decreases its speed according to the amount of gas coming into the boiler depending on the heat demand. This process, called modulation, prevents the boiler from either having too little or too much air in the unit for optimal combustion - ensuring high efficiency.
