What a Complete Quote Request Carries

A request with these items prices without a phone call. A request missing two or three of them still gets a reply; it just starts with questions.

• Product fluid, concentration, viscosity and any particulates or fibers
• Flow rate and inlet / outlet temperatures on the product side
• Whether regeneration (product-to-product preheat) is required
• Utility fluid and its conditions: steam pressure, hot or chilled water, or glycol temperature and flow
• Hygiene class: food-grade drainable, 3-A, or ASME BPE / pharma
• Materials, surface finish (Ra), double tubesheet yes or no, CIP and SIP requirements
• Connections, orientation, space limits and the code or mark required: ASME, TEMA, PED, CRN
• Site conditions: indoor or outdoor, washdown, seismic or other local requirements

How We Size It

The duty comes first: mass flow times specific heat times temperature change on the product side, checked against the utility side so the two agree. Then the log mean temperature difference, corrected for the pass arrangement, tells us how much surface the duty needs at the coefficient each construction can actually deliver on your product.

Viscosity, particulates and the hygiene class pick the construction, and only then does a specific unit get selected. We check pressure drop on both sides against what your pumps and utility can give, confirm the product-side velocity is high enough to keep the surface clean between CIP cycles, and size the unit with a fouling allowance appropriate to the product rather than a generic one.

What you receive is a sized selection with the surface, the pressure drops and the outlet temperatures shown, a price, and a dimensional drawing with connection sizes and locations.
