Retrofit ROI: buyer questions
- How do you calculate refrigeration retrofit payback?
- Take current annual electricity consumption, apply the expected efficiency improvement to get the saved kWh, multiply by the tariff, add any maintenance reduction, then divide the retrofit investment by that annual saving. That gives simple payback in years. A 20% improvement on a plant spending USD 90,000 a year on electricity saves about USD 18,000 annually — a USD 120,000 retrofit pays back in roughly 6.7 years before incentives.
- What refrigeration retrofits give the fastest payback?
- Typically control and setpoint optimisation, floating head pressure, EC evaporator fans, variable-speed compressor drives, door and curtain repair, defrost strategy changes and condenser cleaning or resizing. Full plant or refrigerant conversions deliver more absolute saving but carry longer payback and should be justified on compliance and reliability as well as energy.
- What efficiency improvement is realistic?
- For an older plant with fixed-speed compressors, degraded controls and poor condensing, 15–35% is commonly achievable. For a recently commissioned, well-controlled plant, expect single digits. Ask any supplier proposing an upgrade to state the assumed baseline, the measurement method and how the saving will be verified after commissioning.
- Should downtime be included in retrofit ROI?
- Yes. Model the production or spoilage cost of the changeover window, and the reliability benefit if the retrofit removes recurring unplanned stoppages. On food and pharmaceutical sites the avoided-excursion value is often larger than the energy saving.
- Does ColdMatch carry out the retrofit?
- No. ColdMatch Group connects project buyers with manufacturers and solution providers and structures the requirement into a comparable RFQ. It is not a manufacturer, engineering contractor or lender.
