Overview

CALEFFI 252212HP high performance solar-rated tempering valve has BSP 15mm 1/2" male compression threads at all three ends. Australian Watermark Approved and made in Italy. Caleffi identifies high-performance tempering valves with a yellow cap. The Caleffi tempering valve is compatible and direct swap for most mainstream tempering valve brands such as AVG, AW, Reliance, Tomson and Nefa with same functions, fitment and similar physical size. 

The CALEFFI 252212HP tempering valve is ideal for high temperature and high performance hot water systems, including solar hot water systems, instantaneous heaters, and pumped ring main distribution systems. It automatically mixes the cold and hot water inputs and outputs a steady 50 deg hot water after mixing. The tempering valve is required in Australia by law in the plumbing rules as it is a safety device. Without mixing, the hot water straight from the hot water services can exceed 70 deg and can cause severe instant burns when in contact with skin. 50 deg feels hot, yet without the dangers of burning. When required, the output temperature of the CALEFFI 252212HP tempering valve can be adjusted between 35-50 deg.

NOt good... not great... horrible
Set name: Sublimation Printer
I’m thoroughly disappointed with the Brother Sublimation Printer and would not recommend it. Out of the box, the setup process was more complex than anticipated, with unclear instructions and frequent errors. The print quality was inconsistent, with colors often coming out dull or inaccurate, despite multiple attempts at calibration. I experienced frequent paper jams, which disrupted my workflow and wasted a lot of materials. The printer’s software is buggy and doesn’t integrate well with other design programs, making it frustrating to use. The connectivity options were unreliable, causing frequent disconnections and delays. Additionally, the printer is quite noisy during operation, which can be distracting and bothersome. The build quality feels flimsy and not as durable as I expected. The customer support experience was also poor, with slow response times and unhelpful solutions. I faced issues with ink usage, as the cartridges seemed to run out quickly, leading to higher operational costs. The sublimation prints didn’t have the sharp, vibrant quality I was hoping for, making my final products look less professional. The lack of clear troubleshooting guides added to the frustration. The printer’s design is bulky and takes up more space than I anticipated. Overall, this Brother Sublimation Printer has been a letdown in terms of performance, reliability, and ease of use. I regret investing in this product and would advise looking for alternatives.

Pretty good for the price.
Set name: Sublimation Printer
So far so good. I have been producing a fair amount of items to date. My only wish was that the colors were more vibrant with this printer and it's ink.

Print quality is excellent!
Model: 500N STD
This is my first sublimation printer and I am so happy with my purchase! The print quality is absolutely amazing! I have made a few items and they came out perfectly! The design software and printing software that come with the printer are good but they are really slow. Before you buy, think carefully about what size prints you want to make. This printer only prints up to 8.5x14. Some t-shirt designs are larger than that. The ink is also very expensive. Versiflex ink is much cheaper. It might be worth researching the versiflex model before you commit to this printer.

Huge upgrade from using Eco-tank with sublimation ink.
Model: 500N STD
Wife has been using converted eco-tank printers for a few years with many struggles. The print quality and final result with the Sawgrass prints is a far higher quality and better result!
