Maximum operating conditions Without pump
With pump
Clean saturated steam, up to 6 bar g/165.0 °C (Clean saturated steam, up to 87 psi g/329 °F)
Production
Plant steam, up to 12 bar g/191.7 °C (Plant steam, up to 174 psi g/377 °F)
Primary side
P min. ≥ (P clean steam*1.1) + 0.5 bar g (P min. ≥ (P clean steam*1.1) + 7.3 psi g) Note, If pre-heater option selected, up to an additional 0.5 bar (7.3 psi) of feedwater pressure may be needed in excess of the calculation above depending upon system size and process conditions.
Minimum Supply Pressure (see IM)
Minimum ambient temperature: 32 °F (0 °C) Designed for indoor installation only, protect from freezing.
Feedwater
P-target. ≥ (P clean steam*1.1) + 1 bar g * (P-target. ≥ (P clean steam*1.1) + 14.5 psi g) *This pressure may need to be varied on commissioning, see IM.
Note, If pre-heater option selected, up to an additional 0.5 bar (7.3 psi) of feedwater pressure may be needed in excess of the calculation above depending upon system size and process conditions.
P max 8 bar g/T max 110 °C (P max 116 psi g/T max 230 °F) P max 8 bar g/T max 100 °C (P max 116 psi g/T max 212 °F) Note: Feedwater is recommended to be demineralised or Reverse Osmosis quality to ensure high performance. Energy Efficiency Insulation: - Different options are available to avoid radiation losses – see product nomenclature and selection guide. Flash heat recovery options are available to optimise your system efficiency:
6.1 13
- Localised CSG heat recovery – bespoke feed water preheating solution - EVC – Exhaust Vent Condenser from a Condensate Receiver/Hot well
- FREME - Flash Recovery Energy Management Equipment - Flash Vessel with Steam Jet Thermocompressor (SJT) Please contact Spirax Sarco who can propose an optimised solution with consideration to your wider system. The generator and hot piping should be insulated to prevent thermal losses. Where insulation options don't provide complete coverage, additional insulation should be applied as needed. Option (see nomenclature) Generator Body Thickness (mm) Hot Piping Thickness (mm) 0 - Not Insulated none none 1 - Steam Generator body only 50 mm none 2 - Steam Generator and hot piping only 50 mm 50 mm 3 - Steam Generator body to EnEV specification + hot piping 100 mm 50 mm
Insulation material Rockwool Cladding material Stainless steel 304
