Engineering at its Best

The Environmental Group provides a broad range of engineered products to the industry, such as gas turbine inlet filtration systems (filter houses), inlet cooling/fogging systems, acoustical components, expansion joints and complete exhaust systems with guillotine and diverter dampers. These products are applicable to new systems, upgrades, and retrofits, and spare part supplies. 


While these complete systems are most commonly requested by our clients, we provide a range of other products to cover non-standard applications or specific requests. Our engineering services enable us tailor any of our products to meet clients’ requirements.

Engineering for a Sustainable Tomorrow

Silencers

We specialise in comprehensive acoustic analysis for projects, custom-designing exhaust silencers to meet noise targets efficiently.

We specialise in comprehensive acoustic analysis for projects, custom-designing exhaust silencers to meet noise targets efficiently. These silencers ensure minimal pressure losses while achieving near and far field noise level requirements for gas turbines exhausts, inlet filters and other high flow. We also provide industrial sound barriers as a cost-effective solution for noise reduction from various sources. Provide silencers for gas turbines in the range of 10MW to 500MW, both horizontal and vertical silencer, circular or rectangular.  

Guillotine Dampers

Guillotine Dampers

Used whenever a secondary isolation of the HRSG ducting is required during maintenance works, and are fitted downstream of the diverter damper in a typical Bypass Exhaust System.

We can provide guillotine dampers, either electric or manual operated, and fully automated with the option of providing a Seal-Air System independent of the diverter damper. Custom-designed guillotine dampers can also be supplied for many industrial processes other than isolation of gas turbine exhausts.

Bypass and HRSG Exhaust Stacks

Bypass & HRSG Exhaust Stacks

We excel in the design and manufacturing comprehensive packages for gas turbine bypass and HRSG exhaust systems, encompassing stacks, silencers, and weather dampers.

A crucial component in combined cycle power plants, these systems ensure safe exhaust gas release to the atmosphere and enable efficient gas turbine operation with minimal pressure drop. Our exhaust stacks feature access ladders, landing and ring platforms, and comply with gas turbine manufacturer regulations, incorporating continuous emission monitoring ports on top.

Inlet Filter Houses

Inlet Filter Houses

We design static and pulse-type filter houses, complete with essential support structures.

Static filter houses utilise disposable cartridge-type filters, featuring two filtration levels – coarse pre-filters for larger particles, followed by fine filters. The size is determined by the required interval between filter changes. We also provide necessary ductwork, expansion joints, and silencers for turbine integration if needed.

Evaporative Cooler

Evaporative Cooling Systems

We employ evaporative cooling by drawing turbine inlet air through wet media, naturally cooling it as water evaporates as well as for extreme cold climates, we deliver innovative Heating Systems for Filter Houses.

Our engineers provide custom designs suited to specific environmental conditions on a case-by-case basis.

Diverter Damper New

Diverter Dampers

Engineering custom diverter dampers for gas turbines, ensuring optimal sizing for any application,  providing a sealing efficiency of 100%.

Our portfolio includes the delivery of the largest diverter damper to date: a 6.5m gas path.

Our designs incorporates cold shells with ceramic fibre insulation for diverters, elbows, and exhaust stacks. This design maintains an exterior temperature below 50°C, even with exhaust gas temperatures exceeding 680°C.

Heating & Cooling Systems

Heating & Cooling Systems

We design and install chilling coils inside inlet filter houses to improve the gas turbine performance on hot days.

We also install heating piping (steam or hot water) inside the inlet filter houses to improve part load performance on gas turbine and provide anti icing capabilities when air temperature is below 4oC.
