RHP1000: the BI-K platform in a single 1 MW unit.
A reversible machine that cools the data center and, in the same enclosure, generates electricity on an ORC cycle. Two versions, chosen by where the heat goes.
Nominal data from the datasheets, revision 22 September 2026.
One machine, two configurations.
Not two power ratings, and not two catalogue products. It is the same architecture, with the working fluid chosen according to where the data center's heat ends up.
RHP1000 R600aDC
Product code: KC.0101.00027.00 · Working fluid: R600a (isobutane)
The version for sites within reach of a district heating network. In heat pump mode it lifts the data center's heat to 90 °C and feeds it to the network. When the network is not asking for heat, the cycle reverses and the machine generates electricity in ORC mode.
- 1,210 kWth delivered to the network at 90 °C, at a COP of 5.8
- 71.6 kWel net in ORC mode, when the network is not taking heat
Engagement mode: RHP for DHC
RHP1000 R290DC
Product code: KC.0100.00027.00 · Working fluid: R290 (propane)
The version for sites with no district heating network. The ORC runs in normal operation and the reversed cycle regenerates the ice storage, which then becomes the machine's own cold sink.
- 1,000 kWth rejected in chiller mode, at a COP of 4.6
- 84.8 kWel net in ORC mode on the ice sink, against 26.4 on the ambient sink
- Low-temperature loop down to -8 °C for ice production
Engagement mode: RHP + Storage

Nominal values at the operating points declared in the datasheets.
ORC mode, ambient heat sink at 20 °C
| Parameter | RHP1000 R600aDC | RHP1000 R290DC |
|---|---|---|
| Gross electrical power[kWel] | 80.9 | 38.4 |
| Net electrical power[kWel] | 71.6 | 26.4 |
| Net efficiency[%] | 3.8 | 2.7 |
| Evaporator thermal power[kWth] | 1,915.3 | 1,011.1 |
| Condenser thermal power[kWth] | 1,834.0 | 977.0 |
| High-temperature loop, inlet / outlet (maximum)[°C] | 65.0 / 54.9 (75.0) | 65.0 / 59.0 (75.0) |
| High-temperature loop, nominal flow rate[kg/s] | 45.0 | 40.0 |
| Low-temperature loop, inlet / outlet (maximum)[°C] | 20.0 / 26.3 (40.0) | 20.0 / 26.7 (40.0) |
| Low-temperature loop, nominal flow rate[kg/s] | 70.0 | 35.0 |
The R600aDC runs a higher flow rate on the low-temperature loop, which is where the difference in evaporator power comes from.
Heat pump mode
| Parameter | RHP1000 R600aDC | RHP1000 R290DC |
|---|---|---|
| Electrical power input[kWel] | 212.1 | 217.9 |
| COP | 5.8 | 4.6 |
| Evaporator thermal power, heat drawn from the data center[kWth] | 1,002.3 | 786.6 |
| Condenser thermal power, heat delivered[kWth] | 1,210.0 | 1,000.0 |
| High-temperature loop, inlet / outlet[°C] | 82.1 / 90.0 | 24.1 / 30.0 |
| High-temperature loop, maximum temperature[°C] | 124.0 | n/a |
| High-temperature loop, nominal flow rate[kg/s] | 36.0 | 39.9 |
| Low-temperature loop, inlet / outlet (maximum)[°C] | 65.0 / 58.0 (65.0) | -3.0 / -8.0 (10.0) |
| Low-temperature loop, nominal flow rate[kg/s] | 37.4 | 43.3 |
The R600aDC lifts the heat to a district heating network; the R290DC rejects it to ambient while making ice, which is why the high-temperature loop reads so differently. Machine temperature limits for the R290DC are confirmed in the technical offer.
R290DC in ORC mode: what the cold sink does
| Parameter | Ice sink (2 °C) | Ambient sink (20 °C) |
|---|---|---|
| Gross electrical power[kWel] | 106.3 | 38.3 |
| Net electrical power[kWel] | 84.8 | 26.4 |
| Evaporator thermal power[kWth] | 1,230.6 | 1,011.0 |
| Condenser thermal power[kWth] | 1,129.3 | 977.0 |
| High-temperature loop, outlet[°C] | 57.7 | 59.0 |
| Low-temperature loop, inlet / outlet[°C] | 2.0 / 9.7 | 20.0 / 26.7 |
| Low-temperature loop, flow rate[kg/s] | 35.0 | 35.0 |
Same machine, same 65 °C inlet on the high-temperature loop, same flow rate. Only the cold sink temperature changes.
On the electrical connection. Both versions connect in direct current at 600 – 800 V. This is the single DC bus covered by patent BIT30917, the same platform architecture the mode pages describe, and it makes the unit compatible with high-density rack power distribution.

What the datasheet does not cover yet.
Some figures are not published yet because characterisation is still under way. Saying so here costs less than letting you find out halfway through an assessment.
- Sound power and sound pressure levels
- Refrigerant charge and flammability classification: R290 and R600a are both A3
- Control interface and supervision protocols
- Pressure drops on the high- and low-temperature loops
- Operating limits, turndown range and transition times between the two modes
Let's check the operating point of your site together.
30 minutes of technical analysis: available thermal power, loop temperatures, where the heat goes and which of the two configurations fits.
