Ren Co LTD Compressed Air Engineering

Ren Engineering Solutions (Ren Company Limited) is a Nairobi-based energy service company (ESCO) that helps manufacturers reduce energy waste in compressed air systems, one of the largest and most overlooked sources of energy loss in industrial facilities. Compressed air leaks alone account for 10-30% of total compressed air output in a typical plant. Ren identifies and eliminates these losses through a combination of instrumented audits, engineered upgrades, and a zero-capital-expenditure shared savings model in which the company funds the full project cost and recovers its investment from a pre-agreed share of verified energy savings. The firm has delivered energy reductions of up to 61% at manufacturing facilities including Nestle Kenya, Nairobi Plastics, Iber Africa, and Blowplast.

Services:

• Walkthrough energy audits: visual assessment of compressor types, capacity controls, maintenance procedures, and distribution system issues (pressure drops, storage, leaks, drains) with a written findings report
• Compressed air leak audits using ultrasonic leak detection, with options ranging from basic leak tagging to full leak-loss reporting via a web-based monitoring application
• Full system energy audits with instrumented measurement using thermal imaging, ultrasonic detection, and precision flow meters to quantify energy loss and rank savings opportunities by cost impact
• Specialized audits for plastics manufacturing (cost of air per item), steam/nitrogen/oxygen leak detection, and vacuum system demand-side analysis
• Engineering and optimization: VSD (variable speed drive) retrofits, piping redesign, and full compressed air system upgrades tailored to individual plant requirements
• Zero-CapEx ESCO shared savings: Ren funds the entire project (audit, engineering, installation) and recoups from a pre-agreed share of the verified savings, with performance risk carried by Ren
• Supply of compressed air consumables and spare parts (filters, lubricants) with same-day delivery in Nairobi

Sustainability Features:

• Directly reduces industrial electricity consumption by eliminating compressed air system inefficiencies, with documented savings of up to 61%
• Lowers Scope 2 carbon emissions for manufacturing facilities by cutting grid electricity demand
• The shared savings model removes cost barriers to energy efficiency upgrades, making industrial decarbonisation accessible to manufacturers without upfront capital
• Continuous IoT-based monitoring ensures savings are sustained and verified over time, preventing efficiency gains from degrading
• Supports Kenya’s industrial energy efficiency targets by providing measurable, independently verified energy reductions
