Bock reciprocating water chiller, 100 to 400 kW
Afric Froid Bock reciprocating water chiller, air-cooled: 8 sizes from 100 to 400 kW, compressors: Bock HG semi-hermetic, several per unit, with R134a, R407C or R290. Custom-built, on quote. Choose your size below to see its specifications.
The Afric Froid reciprocating water chiller uses several Bock HG semi-hermetic compressors. These compressors are built for continuous duty and can be opened for servicing: valves, rings and bearings are replaced on site, without changing the compressor. It is the choice of industrial users who want a robust, easy-to-repair machine and low water temperatures, down to glycol water below 0 °C.
The sizes
| Cooling capacity | Water flow (m³/h) |
|---|---|
| 100 kW | 17.2 |
| 130 kW | 22.4 |
| 160 kW | 27.5 |
| 200 kW | 34.4 |
| 250 kW | 43.0 |
| 300 kW | 51.6 |
| 350 kW | 60.2 |
| 400 kW | 68.8 |
Nominal capacity with water from 12 to 7 °C and 38 °C outdoor air, a harder condition than the 35 °C of the EN 14511 standard. Water flow for a 5 °C difference: flow (m³/h) = capacity (kW) / (5 × 1.163). In very hot weather the unit produces less: we size it for the maximum temperature of your site, with the reinforced 50 °C version if needed. Intermediate capacities on request.
Why Bock reciprocating compressors?
- Repairable on site: a semi-hermetic compressor is overhauled instead of replaced, an advantage far from spare parts centres.
- Continuous duty: designed for processes running day and night, in the food industry and in manufacturing.
- Low temperatures: a wide operating range for glycol water and cold processes.
- Capacity steps: several compressors per unit, and the inverter option to vary the speed.
- Refrigerants: R134a or R407C, and R290 with the Bock “HC” versions, designed for hydrocarbons.
Options
- Hydraulic module with circulation pump and second standby pump.
- Storage tank (buffer tank) in galvanized or stainless steel.
- Secondary pumping station with a frequency inverter on the pump.
- Inverter compressors (variable speed).
- Condenser with EC fans.
- Stainless steel plate or shell and tube evaporator.
- Glycol water below 0 °C, heat recovery, reinforced version for 50 °C air.
