The most significant upgrade in Alfa Laval’s recent copper-brazed lines is the introduction of thinner plates.
There is no single “new version” launch event for the CAS 200. Instead, Alfa Laval has continuously upgraded the platform. The current new version (as of 2026) is defined by:
For operators of older CAS 200 units, the recommended action is to contact Alfa Laval Service for a retrofit assessment – especially if control system faults or high fan energy consumption are already observed.

Based on the current market landscape and Alfa Laval’s product evolution, this review covers the Alfa Laval CAS 200 plate heat exchanger (PHE). cas 200 alfa laval new version
It is important to clarify that in Alfa Laval nomenclature, the "CAS" series typically refers to Copper Brazed Plate Heat Exchangers. While the "200" designation is not a standard standalone model number in their broad catalog (which usually runs like CB60, CB110, etc.), it most likely refers to a specific capacity class (~200 kW) or a specific newer plate dimension introduced to replace older, less efficient models.
Here is an informative review of the modern Alfa Laval CAS / Copper Brazed series (focusing on the capacity class relevant to "200").
The Alfa Laval CAS 200 (Central Air System) is a critical component in marine and offshore HVAC (Heating, Ventilation, and Air Conditioning) systems. It is designed to provide treated, temperature-controlled fresh air to accommodation areas on vessels.
There is no officially designated "CAS 200 New Version" as a single, renamed product. Instead, Alfa Laval has continuously evolved the CAS 200 platform. The "new version" refers to incremental hardware improvements, upgraded control systems (often migrating to the Alfa Laval Touch control panel), and enhanced energy recovery features compared to early 2000s models. The most significant upgrade in Alfa Laval’s recent
Current versions focus on:
New version helps meet IMO Energy Efficiency Existing Ship Index (EEXI) and Carbon Intensity Indicator (CII) indirectly by reducing auxiliary power consumption (HVAC is a top 3 energy user on most vessels).
Some EPC 60 units shipped with firmware v1.0 that caused “false water seal failure” alarms. Solution: Update to firmware v1.3 or higher (available free from Alfa Laval’s 24/7 portal).
One of the most praised features in the new CAS 200 is the automated water seal. In older separators, operators had to manually time the sealing water valve. Get it wrong, and the bowl would break the seal, sending dirty oil to the clean tank. The new version uses flow sensors and software logic to maintain the hydraulic seal automatically, regardless of feed pressure fluctuations. For operators of older CAS 200 units, the
Absolutely. Whether you are building a new vessel or modernizing an existing engine room, the new CAS 200 represents the best return on investment in the separator market today. It eliminates the guesswork, reduces physical labor, cuts energy bills, and extends engine life.
The upfront cost is roughly 15–20% higher than the old version’s final price, but the payback period, thanks to energy savings and reduced downtime, is typically under 18 months for a vessel operating at sea 200+ days per year.
For marine and industrial engineers tired of wrestling with gravity discs, water seals, and unexpected shutdowns, the CAS 200 Alfa Laval new version is not just an upgrade—it is a professional liberation.
The disc stack in the new version has been redesigned with Nanospin™ technology. While the physical disc count remains similar (approx. 110–120 discs), the gap geometry has been optimized to:
