Proposal No. Q10722
Date: March 19, 2018

PROPOSED LUDELL TUBE AND SHELL HEAT EXCHANGER PERFORMANCE:
• RAISE 145 GPM of INCOMING PROCESS WATER FROM 38 F to 108 F when;
• 150 GPM of WASTEWATER PASSES THROUGH THE HEAT EXCHANGER at an AVG. TEMP. of
120 F with a DISCHARGE TEMP of 52 F.

ESTIMATED ANNUAL VALUE OF HEAT RECOVERY FOR HOT WATER MAKE-UP SYSTEM:
Based on your PROCESS WATER TEMPERATURE of 38 Deg. F:
• Your Potential Reclaimed Heat is equivalent to approx. 151 Boiler Horsepower or
5,230 Pounds of Steam per Hour
• With Your Projected Cost of Steam at $11.00 per 1,000 lbs., YOUR Recovered Heat has a value of
$149,635.00 PER YEAR!

It is easy to see why the benefits and payback of installing a tube and shell heat exchanger support
the upfront costs. Ludell is pleased to quote the following equipment to be incorporated in your
existing water system:
