Overview
Shell-and-tube steam-to-water heat exchangers (also called steam calorifiers) are the primary hot-water generation method for commercial laundry, hotel, and hospital operations that already run a steam boiler. Steam flows through the tube bundle while water circulates on the shell side (or vice versa), delivering continuous hot water at controlled temperature — typically 60°C to 90°C. Compared to electric or direct-fired water heaters, steam calorifiers are dramatically more efficient when boiler steam is already available for process use. Our units come in U-tube, floating-head, and fixed-tubesheet configurations with SS316L tubes for durability against chlorinated water. Sized from 50 kW to 5,000 kW thermal output, fully documented with performance curves and TEMA compliance.

Applications
What Determines Your Quote
Every quote is engineered to your operating requirements. Pricing depends on:
- Configuration: capacity, flow rate, head pressure, motor size, voltage/phase, materials of construction
- Certification tier: WRAS-cert vs commercial-grade, ASME stamping, IP rating for panels
- Delivery region: nationwide (Metro Manila, Luzon, Visayas, Mindanao); freight varies by destination
- Installation scope: supply-only, supply + mechanical install, or full turn-key with commissioning
- Payment structure: milestone terms tailored to project timeline (typically 40/30/20/10 for engineered scopes; 70/30 for equipment supply)
- Tax status: 12% VAT applies to VAT-registered buyers; Zero-VAT available for eligible PEZA / SBMA locators and exporters

Frequently Asked Questions
What certifications come with a steam-to-water heat exchanger?
Our steam-to-water heat exchangers are designed and built to ASME Section VIII and TEMA standards, carry CE marking, and come from ISO 9001:2015 certified production. Every unit ships with material test certificates for the shell and tube bundle (SS304 or SS316L, per your specification), factory inspection reports, and hydrostatic test records at 1.5 times working pressure, so your compliance file is complete on delivery. TEMA compliance matters because it defines the mechanical design rules for shell-and-tube construction; if your consultant specified a TEMA type such as BEM, AEM, or NEN, we match the documentation to it. If your project requires additional third-party inspection or witness testing, raise it during inquiry and we will confirm the arrangement in your written quotation. Documentation questions are answered within 1 business day, and full quotations follow within 3 to 5 business days.
What is the standard lead time for a steam-to-water heat exchanger?
Standard lead time for a shell-and-tube steam-to-water heat exchanger is 45 to 75 days from confirmed order, since each unit is fabricated to your thermal duty, tube material, and TEMA configuration rather than pulled from a shelf. Smaller calorifiers in the 50 to 500 kW range generally land at the shorter end, while large units toward 5,000 kW with floating-head construction or SS316L throughout take longer to fabricate and test. The committed schedule for your specific unit is confirmed in your written quotation, issued within 3 to 5 business days of receiving your duty requirements (available steam pressure, water flow rate, and target outlet temperature). If the exchanger is part of a larger boiler plant order, we can align the delivery schedules so everything arrives within the same installation window rather than in scattered shipments.
Do you deliver heat exchangers to Luzon, Visayas, Mindanao, SBMA, and Clark?
Yes, we deliver heat exchangers nationwide: Metro Manila, all Luzon provinces, the Visayas, and Mindanao, including SBMA, Clark, and the PEZA industrial estates where many of our clients operate. Shell-and-tube heat exchangers travel well as crated cargo, so freight is straightforward compared to bulkier plant equipment; delivery cost is quoted per project based on unit size and destination. For provincial and island deliveries we consolidate with our regular logistics runs where possible to keep freight costs sensible, and we coordinate the delivery date with your site team so the unit is not sitting exposed on-site ahead of installation. Give us the delivery address, any offloading equipment available on-site, and your target installation date during inquiry, and delivery appears as a clear line item in your written quotation. We respond to inquiries within 1 business day.
Is installation included with a heat exchanger, or is it supply-only?
Both supply-only and supply-plus-install are available, quoted separately so you can compare the two arrangements on cost. Supply-only suits plants whose mechanical contractor is already on-site piping the steam line: the calorifier arrives with full performance documentation and your team handles mounting, steam and water connections, trap sets, and controls integration. Supply-plus-install adds positioning, hookup coordination, and commissioning support so the unit is verified to deliver its rated outlet temperature under real load before handover. A heat exchanger is only as good as its installation: an undersized steam supply, missing traps, or poor condensate removal will drag performance well below the datasheet, so if your team has not installed a calorifier before, we recommend at least taking the commissioning support. State your preference during inquiry and both options can be priced side by side in your written quotation.
What warranty does a steam-to-water heat exchanger carry?
Warranty coverage for a steam-to-water heat exchanger depends on the configuration, tube material, and duty conditions, so the specific period and inclusions are confirmed in your written quotation rather than quoted as a blanket figure. Every unit ships with material test certificates, factory inspection reports, and hydrostatic test records, which give you a documented baseline condition for any future claim. Claims run through our team as your single point of contact, and coverage assumes the unit operates within its rated steam pressure and temperature with proper trap and condensate arrangements, which is standard for pressure equipment. Shell-and-tube construction is also inherently serviceable: the removable tube bundle means most issues are repairable on-site rather than requiring unit replacement, which matters over the long service life these units deliver. Ask for the warranty annex with your quotation.
Can you customize a heat exchanger to a non-standard specification?
Yes, and in practice most heat exchanger orders are customized to some degree. Thermal output is sized anywhere from 50 kW to 5,000 kW, with U-tube, floating-head, or fixed-tubesheet construction, SS304 or SS316L tube bundles, and carbon steel or stainless shells specified per project. Water outlet temperature is controlled between 60 and 90 degrees Celsius via the integrated PID controller, and options such as cathodic protection for chloride-heavy water, inspection ports, and insulation-ready shells are added where the duty demands them. To size the unit correctly we need your available steam pressure, required water flow rate, and target outlet temperature; if you only know the downstream equipment (washers, hot water loops, sanitation stations), send that instead and we will calculate the duty for you. Custom configurations are quoted in writing within 3 to 5 business days.
