Chandlers Keromax Q & A’s

Q: How does Chandlers Keromax work?                     
A: Chandlers Keromax has special ingredients that help avoid fuel degradation, carbon deposits and other operating problems that routinely occur.

Q: Can I mix Chandlers Keromax with the kerosene in my tank?
A: Yes, they will be completely compatible. Depending upon how much regular kerosene is already in your tank and the quality of it, the full benefit may not be achieved until the second or even third fill.

Q: Will there be any adverse effects to the product in very cold or very hot temperatures?
A: No, Chandlers Keromax will not be affected by extremes of weather, in fact this fuel will remain fresher for longer in very hot temperatures.

Q: I have read that Chandlers Keromax works by avoiding deposits and operating problems that can occur, but does it also instantaneously burn better in an existing clean system or have higher energy content (e.g. calorific value?)
A: No.Chandlers Keromax has the same energy content as regular kerosene.  It works by avoiding fuel degradation, deposits and other operating problems that routinely occur with systems operating over several weeks due to the special additives.  Instantaneous ‘combustion-improvers’ often have side effects that can cause damage to your boiler. Chandlers Keromax does not contain them.

Q: Will any warranties on my boiler and equipment be affected?
A: No The product meets the same Fuel Standard (BS2869C2) as normal kerosene and therefore should not have any effect on any warranties.

Q: Will Chandlers Keromax be compatible with my boiler and do I need to consult my boiler engineer or boiler manufacturer first?
A: Chandlers Keromax meets the same BS 2869C2 specification and is therefore compatible with your boiler if you are currently using regular kerosene. You do not need to consult your boiler manufacturer or heating engineer before using Keromax.

Q: I have told my boiler engineer about Chandlers Keromax and he has some technical-type questions that I cannot answer. Is there anyone we can talk to who can answer his questions?
A: Yes. Please contact us and we can put you in touch with someone who will be able to answer these.

At present we remain fully operational and are conducting deliveries as normal. All staff are taking appropriate measures regarding personal hygiene and managing their own particular circumstances, which may include self-isolation.

To protect our drivers, we have asked that they limit contact with customers where possible. Ideally no contact is preferable. We are asking that POD’s are not signed as an additional pre-caution.
The wellbeing of our staff and customers will always be our number one priority. As such, we have implemented several changes to our normal working practice, including:
• A restriction on all travel unless business critical
• Field Representatives working from home or office based
• No longer attending remote meetings
• Cancelling all non-essential travel to conferences and staff training events
• No longer allowing visitors to site
• Increasing our focus on hygiene and cleanliness in both our offices and cabs
We trust you appreciate the need to play our part in reducing the risk of spreading the coronavirus to keep us safe.
