Formerly ACME series refrigerant condensers, these Ketema Brand design condensers offer 22 models ranging from 24 to 380 nominal HP. This reliable design has been available for over 30 years and the dimensions are virtually unchanged.
Standard Designs
MHX Ketema Marine condensers are available in these standard designs for seawater duty. For R410A duty please consult the ProSuite sizing software or contact the factory.
Tube Materials
MHX marine condensers are manufactured with enhanced 3/4″ OD 90/10 cupronickel tubing to provide reliable performance and ease of service from commonly available tube cleaning devices.
Customization
As standard, these units offer horizontal, cleanable tube design. Custom vessels are available with special materials of construction as required.
Water Flow
Velocities of 6.6 feet per second (ft/s) or higher risk premature impingement corrosion and tube failure. Operation below minimum flow rates may result in excessive fouling and poor heat transfer. All values in this shown on the dimension tables are limited to flow velocities below ten feet per second. Water flow rates for shallow water applications need to be below seven feet per second due to a higher risk of premature impingement corrosion or tube failure, units should not be used without upstream filtration to lower failure risks.
Alternative Options
For higher pressure, refrigerants use MSE-MP units or consult factory for MHX-MP (Multi-Pressure). For greater pump down capacity consult factory for MST units.
Custom and larger models are available, please contact your local sales representative
