The display constantly shows the temperature measured from the inflow pipe, with a one-decimal-place accuracy.

Teco had already given us a preview during a visit to their office, where we had the chance to see it alongside the other chillers, one of which, the Teco TK 500, we reviewed a few months ago here.

Lets look at the technical features of these four chillers, completely redesigned and very different from the previous line, to which the Teco TR 15 belonged ( review ).

The TR 15 was a parallelepiped, while the three new, larger TKs are almost cubic.

The TK 500, 1000 and 2000 are constructed with the same base but different heights, as you can see in the following picture.

The TK 150 is unique; it still is a parallelepiped like the old TR 15 but in a naked version.

Manufacturing The new Teco Tank TK 150 Aquarium Chiller has been completely redesigned, and is unlike any of the older models.

The shape remains parallelepipedal, but is totally open Its base measures only 2136 cm, and it is 31 cm tall.

The convective hot air movement and the fan help dissipate the coils heat, which, for construction reasons, doesnt need an air filter.

The inout water pipes are positioned at the top and bottom of the unit, and they have a 12 mm diameter (12), smaller than the larger-sized chillers 34 pipes.

To fasten the tubes to the pipe joints, two cable ties are included.

They are a bit hard to use, but they definitely secure the tubes, guaranteeing a completely watertight seal.

The red liquid crystal display has been enormously improved, in comparison to the previous models, its a shame we cannot appreciate it in the picture above (its off).

To review, just watch the video below; we created it especially for the new Teco Tank Chiller Line, and it covers the TK 150 and the three more powerful units.

The Probe One notable detail is the position of the temperature probe.

Teco placed the probe in the inflow pipe to make sure that the temperature measured is the actual one from the tank, which hasnt been cooled yet.

This is one of the reasons why we did not notice a drop in temperature on the display shortly after turning the chiller on.

This could lead to frequent onoff cycles of the unit without an actual lowering of the tank temperature.

Installation The installation is very easy, we just need to connect the inout tubes and then connect the inflow tube to a return pump (or a deviation of the existing return pump).

Before each use, I strongly recommend a cleaning cycle: remove it from the sump and place the pump and tubes in a water bucket with muriatic acid (hydrogen chloride) at 5 concentration, then let everything run for 10 minutes to dissolve any trace of limescale.

When set up with an adequate return pump Teco recommends a minimum of 400 lh there is very low noise overall, most of the noise comes from the fan rather than the compressor.
