Technical Specifications：

Key Features：

• Skid-Mounted Assembly: The hotwell tank, atmospheric condenser, boiler feed pumps, valves, and piping are mounted on a single base frame.
• Pre-Shipment Testing: The complete unit undergoes sealing and operational running tests at the factory before delivery.
• Water Treatment Functions: Contains an integrated filter for removing oil and contaminants. The tank design allows for chemical dosing to alter water properties.
  
• Customizable Interfaces: The location of all external connection points for piping can be manufactured according to the ship’s arrangement drawings.

Applications：

• Steam condensate collection and treatment systems on military and civilian ships.
• Boiler feedwater supply systems for vessels with oil-fired or exhaust gas boilers.
• Relevant steam and feedwater systems on offshore drilling platforms.

Installation & Maintenance：

Installation: The unit is delivered as a single module. The base frame must be secured to the ship’s foundation. External system interfaces must be connected to the corresponding ship piping.
Maintenance: Regular maintenance tasks include monitoring pump operation, cleaning filters, and managing water treatment chemical levels within the hotwell tank.

FAQ ：

Q: What is the main benefit of an integrated hotwell unit?

A: It reduces on-site installation time and labor because the primary components are assembled, piped, and tested at the factory before shipment. It also ensures component compatibility within the unit.

Q: What type of pumps are used?

A: Marine-grade boiler feed pumps, typically multi-stage centrifugal pumps, are selected based on the boiler’s required pressure and flow rate specifications.

Q: Can the unit receive condensate from multiple return lines?

A: Yes, the inlet piping and hotwell can be designed to receive and manage condensate from various return lines on the vessel.
