Steam Calorifiers
Royles Non Storage Calorifiers
1. What is the difference between a boiler and a water heater?
A boiler produces hot water or steam at temperatures exceeding 100°C.
Water heaters produce hot water up to 85°C.
2. Do you make both boilers and water heaters?
Heat Transfer do not manufacture boilers, but we do manufacture various water heaters.
3. What anti corrosion liners do your vessels come manufactured with?
Different linings are used dependent on the geographical location.
Coastal conditions are more aggressive than inland and require a more durable lining.
4. What is the guarantee period on your vessels?
Two years on all vessels with Hotline 75 and Phenoline 1205 (5 years available on request) as well as 5 years on Polyglass VEF linings.
All electrical components carry a 12 month warranty.
Conditions of sale and warranty available on request.
5. Do you deliver?
Yes, we will deliver within roughly 200km radius.
Delivery to further sites can be arranged at an additional fee.
6. What is your turn around time from date of order?
Generally 3 – 4 weeks dependent on work loads.
7. Do you do installations?
On request.
- The HT “RNS” Series Non Storage Calorifiers are external water heaters using steam as primary heat source and designed and manufactured generally in accordance with the ASME VIII code of practice, from mild steel and in compliance with the Machinery and Occupational Safety Act, with all steam heads independently certified to meet the Factories Act requirements.
- Manufacturing Specification (Royles Non Storage Calorifiers)
- Manufacturing using our patented ROYLES patented indented copper tubes for supreme efficiency.
- Steam domes are certified by an Independent Test Authority.
- Available in both vertical and horizontal models.
- Insulation is by means of 75mm fibre wool, clad with 0.6mm galvanised sheet metal, with stainless steel or aluminium on request.
- Storage Calorifers are generally galvanised, or coated with Stoncor Hotline 75 , Phenoline 1205 Glass flake epoxy or Polyglass linings are available on request. Non Storage Calorifiers (RNS ) are only available in Galvanized.
- Practical heating ranges from 75Kw to 6000Kw (see table below).
- ROYLES Indented Tube is used in all storage and non-storage calorifiers manufactured by Heat Transfer Engineering and is totally unique in design. Design characteristics of the ROYLES indented tube provides the following advantages:
-
- Heat transfer inefficiencies caused by formations of air and condensate film is minimized by an internal turbulence created by the indents in the tube.
-
- Indents allow the tube to expand and contract which helps prevent the build up of external deposits, again improving heat transfer efficiency.
-
- Tubes may be individually removed, which reduces maintenance costs and downtime.
-
- Physical size of the plant is reduced resulting in more compact and efficient units.
