Evaled - Model PC R Series - Evaporators for Industrial Wastewater Treatment
From Evaporators - Evaled - PC - Heat Pump
PC R series evaporators combine the versatility of heat pump technology with the effectiveness of the scraping system installed inside the boiling chamber. The combination of these two technological solutions therefore allows the treatment of wastewater at low temperatures (max. 40° C), offering the opportunity to achieve high degrees of concentration. Scraped evaporators with heat pump and forced circulation.
Product Details
The PC R series is designed for the treatment of particularly difficult handling liquids such as viscous, saline or sediment-containing liquids, and is also the ideal solution for the treatment of pre-concentrated liquids with the aim of maximum volume and cost reduction in waste water disposal.
The quality of the distillate produced makes it suitable for reuse within the company, which can range from regeneration of process baths to secondary uses, thus reducing supply costs and water impact.

SUPERDUPLEX and AISI316: different materials of construction to handle even the most aggressive effluents (acid pH, chlorides, heavy metals)
The drastic reduction in wastewater volumes means that disposal costs are reduced accordingly, making a return on investment often quantifiable in months possible.
The right choice when:
- the effluent to be treated has a high content of suspended or dissolved solids
- the waste to be treated is already pre-concentrated
- the daily volumes to be processed are relatively small
- a high reduction of the volume to be disposed of is required
Operational Advantages
- Low operating costs
- Automated unit
- Remote control
- Ease of use
- Semi-continuous working mode
- Tailor-made Service Packages
- Rental possibilities
All EVALED evaporators are standard and modular, frame-mounted automated units to minimise the space required, require minimal labour and maintenance, and are ready to use (plug & play).

How it Works
How EVALED® evaporators work
A multi-effect evaporator uses the steam produced inside the first boiler to produce new steam in the second, at a lower temperature and pressure. This steam recycling can be cascaded (multiple effect) depending on the temperature of the first fluid heating step and the fluid cooling step during the last process. Although it is possible to go beyond two effects, above this number the investment cost becomes considerable and a solution involving a mechanical recompression evaporator becomes more efficient.
HOW DOES A MECHANICAL VAPOR RECOMPRESSION EVAPORATOR WORK?
A mechanical vapor recompression evaporator or MVR utilizes the vapor generated inside the boiling chamber. This is compressed adiabatically (energy consumption depends on the compressor) with very high efficiency, the temperature rises and condensation takes place in the main heat exchanger, which transfers latent heat to the fluid to be evaporated. Furthermore, an auxiliary heat recovery system further optimizes the already extremely low energy consumption (approximately 35-40Wh/liter water, 25 times less than atmospheric evaporation).
