This Equipment Proposal for a HEAT RECOVERY SYSTEM has been designed by Ludell Engineers and was
based upon requirements and data contained in the Request for Proposal provided by your facility.

For your review, this proposal includes:
• An energy savings projection and heat recovery value calculation
• An itemized description of requested equipment, optional add-ons, and associated costs
• Ludell guarantees, warranty, terms, and conditions

ENERGY SAVINGS PROJECTION

CUSTOMER PROVIDED DATA:
Wastewater Consumption @ 20% Evaporation …………………………… 30,148,843 Liters per Week (790 GPM)
Hot Water Make-up Flow ……………………………………………………………. 27,989432 Liters per Week (733 GPM)
Wastewater Temperature …………………………………………………………………………………… 55 Deg. Celsius (131 F)
Cold Process Water ……………………………………………………………………………………………. 27 Deg. Celsius (80.6 F)

TEMPERATURE RISE GUARANTEE FOR HOT WATER MAKE-UP SYSTEM:
Our Proposed Heat Recovery System will:
• RAISE 733 GPM of INCOMING PROCESS WATER FROM 80.6 F to 116 F when
(Reclaimer Design with a 10 Degree Approach)
• 790 GPM of WASTEWATER PASSES THROUGH THE HEAT EXCHANGER at an AVG. TEMP. of
131 F with a DISCHARGE TEMP of 97 F.

ESTIMATED ANNUAL VALUE OF HEAT RECOVERY FOR HOT WATER MAKE-UP SYSTEM:
Based on your PROCESS WATER TEMPERATURE of 80.6 F:
• Your Reclaimed Heat is equivalent to 387.5 Boiler Horsepower or
13,370 Pounds of Steam per Hour
• With Your Steam Cost of $9.79 per 1,000 lbs., YOUR Recovered Heat has a value of
$1,144,843.00 PER YEAR (Based on 168 hours per week at 52 operating weeks per year)
