Fernox Alphi-11 Antifreeze Protector 5L (liquid) 61033 product description:

Available in a 5 litre liquid product, Antifreeze Protector Alphi-11 is compatible with all other Fernox products.

Antifreeze Protector Alphi-11 is a combined antifreeze and inhibitor product, which provides protection against internal corrosion and limescale formation in domestic central heating systems.

Antifreeze Protector Alphi-11 is suitable for use with all metals and materials commonly used in heating systems. For long-term protection ensure concentration levels are maintained and checked annually as part of the boiler or system service.

Application, Fitting & Dosing The minimum recommended ‘in-use’ concentration of the product is 25% in order to ensure adequate corrosion protection.

This concentration will protect down to -11 °C. A concentration of 40% will protect down to -22 °C. Alphi-11 Antifreeze Protector can be introduced via the feed and expansion tank, or injected directly into the system via a suitable point (e.g. dosing pot). Introduce into the system after draining off a quantity of water at least equal to the amount of Alphi-11 to be added.

Engage the circulating pump and have the system online for a few hours in order to achieve an even distribution. Concentration 25% 30% 35% 40% Protection -11 °C -15 °C -18 °C -22 °C.

In single feed indirect cylinders, e.g. “Primatic” or similar, potable water chemicals must be used. We recommend untreated systems are thoroughly cleansed and flushed, in accordance with BS 7593:2019 and Benchmark, using Fernox Cleaner F3, before treating with Fernox Alphi-11 Protector, as existing debris can damage the installation. Package, Handling & Safety Fernox Alphi-11 Antifreeze Protector is supplied in 5 and 25 litre containers.

Calienta de manera uniforme
Color: Lavender, Size: 15"x15" 8 in 1
Estoy muy satisfecha con esta máquina de calor. Calienta de manera uniforme y mantiene bien la temperatura, lo que ayuda a que los diseños queden con buen acabado. Ha sido fácil de usar incluso para alguien que está comenzando en el mundo de la sublimación y personalización. La he usado para diferentes proyectos y los resultados han sido muy buenos. También me gustó que es resistente y no ocupa demasiado espacio. La recomiendo para personas que quieren iniciar un emprendimiento o ampliar sus trabajos personalizados.

Slow support
Color: Green, Size: 15"x15" 8 in 1
Seems to work ok. It is lighter than expected which is a plus. Support is very slow from company and did not come with instructions. You have to email them for a pdf copy.

Temp Sucks
Color: Black, Size: 12"x15" 5 in 1, Color: Black, Size: 12"x15" 5 in 1
I got the 8in 1 inset wad of the 5 in 1 that I had originally ordered. The seller contacted me about because it was the holidays they decided to send me the 8 in 1. I never had any trouble with the mug press before. My temp was 365 for 60 seconds and the burning never happened before. Then I put my cup in and my press started to smoke. The sublimation paper started turning brown and smelling bad. So I turned the temp and time down to 345 for 30 seconds. But when it was time to press it, the temperature went over 500 and started rising. So I turned it off and turned it back on but it did the same thing. I don’t know what to do. I can’t get a refund or even return it. This mug press sucks. Don’t waste your time!!! %%Update%% I can’t do this anymore. This was the replacement they sent me and it already burned my tumbler. I only used 330 for for 30 seconds and after the first turn the paper was brown. Then it started smoking. I can’t keep wasting tumblers on the mug press. My room smells like smoke. This never happened before. I used 6 tumblers in this machine before it started smoking. I’m going to buy another tumbler press. Not from here. &&Update&& They sent me an entirely new machine with attachments. I think the problem was the control box but now I have doubles of everything
