PolyDome/PolyTank
Dick Johanneck started Polytank, Inc. in 1972 doing custom rotomoulding. In 1977, he began making calf hutches which became known as Poly Dome Calf Nurseries. The agricultural products division of Polytank was later named PolyDome. Since that time, Polytank and PolyDome have added over 200 products to their line. Polytank has dealers scattered across the United States, Canada, and 10 foreign countries. The rotomoulding process uses hollow metal moulds and powdered polyethylene plastic that become liquid under high heat. The moulds with the liquid plastic inside are spun on both vertical and horizontal axis to form a uniform thickness, or skin on the outside walls, thus the name rotomoulding. The mould is removed from heat and allowed to cool under controlled conditions to avoid shrinkage or warpage. The resulting polyethylene plastic product is resistant to impact, most corrosive chemicals and temperature extremes.

About Us
Over 40 years of experience in developing calf hutches, Polydome has over 200 agricultural products and dealers scattered across the United States, Canada, and 10 other foreign countries.
The slippery surface makes it very easy to clean. Polyethylene is also environmentally friendly because it can be recycled.
Most PolyDome products are one piece with no seams or sharp edges. The light weight of polyethylene makes even large units easy to lift and move. PolyDome has their own metal fabricating shop for frames, stands, and supports used with their agricultural products. All metal parts are powdercoated for corrosion resistance.
A Hutch for All Seasons
Performance tests rate polysquare as top pick for raising calves Reprinted from the “Ontario Milk Producer” July, 1999
Polysquare hutches are being recommended by a University of Guelph researcher as the best hutch housing for dairy calves after performance tests conducted at Kemptville College.
Most dairy farmers begin using individual dairy calf hutches to prevent disease. Other benefits include durability, easier sanitation, and improved welfare and overall health of the calves.
During the two-year trial, Dennis McKnights compared four different kinds of hutches:
- Polysquare hutches, made of thermomoulded opaque polymer with ridge-top and side-adjustable ventilation.
- University of Virginia hutches, with latticed front and sloped metal roof.
- Traditional wooden huntches;
- Polyethylene domes
McKnight evaluated the structures on the basis of cost, durability, portability, ease of sanitation and calf performance. The polysquare ranked first in each category except calf performance and cost. Calves housed in the polysquare hutches grew nearly as well as calves housed in University of Virginia hutches and better than calves in traditional wooden hutches and polyethylene domes.
At about $400 each, polysquares are more expensive that either the wooden or University of Virginia hutches but comparable to the polyethylene domes, already used on many Ontario farms. Although the wooden and University of Virginia hutches are less expensive, they’re also less durable and need replacing sooner than either squares or domes notes McKnight.
As well, polysquares and polydomes are easiest to clean. This may help prevent illness when a new calf moves into one.
The research results also suggest air quality improves calf performance. Hutches with good ventilation, like the polysquares, were superior to those with poor air circulation, such as the polydomes. The domes became excessively hot during the summer and fall, and calves had to be allowed outside to cool off. However, the polysquare hutches had built-in vents and superior air exchange.
McKnight’s study involved 160 calves in tests conducted twice in every season over a two-year period. He had expected different hutches would perform better in either cold or warm weather, but this was not the case. The polysquare and University of Virginia hutches were superior in calf performance over other choices in every season.
Based on the overall results, and especially on dura-bility, ease of sanitation and portability, McKnight recom-mends polysquare hutches over all others. However, McKnight stresses, hutch choice is no guarantee of good calf performance. There are other important factors to consider.
“Regardless of what is chosen, proper management and maintenance of the calf is important,” he says. “Hutch type is only a piece of the puzzle. It seems to offer a beneficial environment for calf health by keeping it clean and dry.”

History
1972
Dick Johanneck started Polytank, Inc. in 1972 doing custom rotomoulding, which resulted to polyethylene plastic product that is resistant to impact, most corrosive chemicals and temperature extremes. It’s lippery surface makes it very easy to clean and it is also environmentally friendly and recycleable. Polydome products are made from this material.
1977
In 1977, Dick began making calf hutches which became known as Poly Dome Calf Nurseries. The agricultural products division of Polytank was later named PolyDome.
1978
From 1977 onwards, Polytank and PolyDome have added over 200 products to their line. Polytank has dealers scattered across the United States, Canada, and 10 foreign countries.
Today
Most PolyDome products are one piece with no seams or sharp edges. The light weight of polyethylene makes even large units easy to lift and move. PolyDome has their own metal fabricating shop for frames, stands, and supports used with their agricultural products. All metal parts are powdercoated for corrosion resistance.
High Quality Agricultural Products
We at Polydome believe that today’s calves are tomorow’s profits. We help our customerts put money back into their pockets faster while providing the best in quality. Why risk burnt lungs, frozen ear and tails when you can elimate ammonia? Most of ouer products are in one piece with no seams or sharp edges.

Quality Plus Experience
The Polydome convertible indoor Calf Nursey is a whole new approach to calf hutches. This calf nursey is intended to be used indoores to keep calves seperated to prevent diseases and promote healthy growth. It works very well in cold climates where outdoor hutches do not stay warm enough in the winter.
