During the past 34 years of cooling tower testing,
the staff of CTTA has developed or improved numerous items used for cooling
tower testing. The items which are available from CTTA are listed below
(

WET BULB INSTRUMENTS
The improved design of the CTI wet bulb instrument consists of a chrome-plated instrument body, with 115 Volt 50/60HZ fan/motor assembly, wick, 250-ml polycarbonate water bottle with bottle mounting bracket. Wet bulb instruments are usually sold in pairs with foam lined suitcase. (requires 15" long thermometer or RTD probe to be purchased separately)

REINFORCED PITOT TUBE
The CTTA design improved the Simplex pitot tube by providing a stiffer tube than used in the Simplex design. It uses the Simplex flat rod and pitot tip components as its basis and has a 1-1/2 inch diameter by 1/4-inch wall stainless steel reinforcing tube. The O-ring packing gland used in CTTA pitot tubes results in lower friction than that of the Simplex stuffing box design and makes the tube easier to move in and out of the pipe. The packing gland has 2-in NPT male threads for attachment to a pitot tap or port. The overall length of the modular style tube is approximately 3-ft more than the working length. The modular style tube can have interchangeable shaft lengths. Allowance must be made for the pitot taps or ports in the pipe to insert the tube. Typically, the working tube length should be 1 to 3-ft longer than the pipe diameter to be traversed. Consult CTTA before ordering.
Reinforced Pitot Tubes (4-ft to 17-ft
working lengths)
| New modular fixed tip style pitot tube (base price) | $2,500.00 |
| New modular length charge (per foot) | $100.00 |
| Extra shaft for modular fixed tip style pitot tube (base price) | $500.00 |
| Extra shaft, modular length charge (per foot) | $100.00 |
(Example: for a 10-ft pitot tube, cost = $2,500.00 + 10 X $100.00 = $3,500.00) |
|
Pitot Shipping/Storage Box With Handles, Latches and Hinged Lid
| Pitot shipping/storage box (base price) | $300.00 |
| Length charge (per foot) | $15.00 |
(Example: for a 10-ft pitot tube, cost = $300.00 + 10 X $15.00 = $450.00) |
|
