Process water at 80, 95 or 120 °C — without burning anything.
Two-stage cascade refrigeration delivering true high-temperature water for CIP, sterilisation, dyeing, washing and drying duties. Where a boiler runs at 80% efficiency, these run above 300%.
How it reaches temperatures other heat pumps cannot.
Two-stage cascade circuit
A low stage lifts to an intermediate temperature and a high stage takes it the rest of the way, each working in its efficient band.
Return temperature is the variable
These units are selected on your return temperature. A 70 °C return costs far less to lift than a 30 °C one.
Waste-heat source options
Ambient air, chiller reject, compressor jackets or process effluent — whichever is warmest and steadiest.
Stainless and titanium wetted parts
Specified against your water chemistry, including CIP caustic and acid cycles.
Cascade with base-load plant
Pair with TT-CM for the 60 °C portion so the expensive stage only does the top lift.
Metered verification
Energy and thermal metering as standard, so the COP claim can be checked against the design figure.
TT-HT model range.
Nominal figures at 25 °C ambient with a 70 °C return temperature.
| Model | Heating kW | Max flow °C | COP | Supply |
|---|---|---|---|---|
| TT-HT 30 | 30 | 80 | 3.4 | 415 V 3φ |
| TT-HT 60 | 60 | 80 | 3.4 | 415 V 3φ |
| TT-HT 90 | 90 | 95 | 3.1 | 415 V 3φ |
| TT-HT 150 | 150 | 95 | 3.1 | 415 V 3φ |
| TT-HT 240 | 240 | 120 | 2.7 | 415 V 3φ |
| TT-HT 350 | 350 | 120 | 2.7 | 415 V 3φ |
COP figures assume a 70 °C return. Selection requires a week of logged flow and return temperatures — we will not quote a high-temperature unit without them.
Duties this range was built for.
High-temperature heat pumps replace boiler load, not boilers. Steam duties stay with the boiler; hot water duties move.
- Pharma CIP and sterilisationClean-in-place cycles at 80–95 °C with documented temperature holding.
- Dairy and food processingPasteurisation support, bottle washing and plant sanitation loops.
- Textile dyeing and finishingDye bath and rinse water at 95 °C, typically 50–65% of total boiler load.
- Commercial and hospital laundriesWash and rinse at 85 °C, with recovery from the drain to lift the return temperature.
- Automotive and metal pre-treatmentDegreasing and phosphating baths held at stable temperature.
A week of logged flow, return and batch timings. Without it, any COP number is a guess and we will not put one in writing.
Ask an engineerHow much of your boiler load can move?
Send a loop schematic and a week of logged temperatures. We will tell you what is realistic, including what stays on the boiler.
